Answer 1
the answer is C, 40, angle c for triangle abc is 50 bc the total of it and 130 must equal 180. so if you subtract the angle you are given, 90, and the new angle, 50, from 180 (total a triangle should have) then your answer is 40.

The three angles of a triangle measure x+37, 90, and x+67. Find the measurement of the smallest angle in degrees.
Please help!!!

Answers

Answer:

The first angle is the smallest

Step-by-step explanation:

Step one:

given data

Angle 1= x+37

Angle 2= 90

angle 3= x+67

We know that the sum of angle in a triangle is 180

so

x+3+90+x+67= 180

collect like terms

2x+160= 180

2x=180-160

2x= 20

divide both sides by 2

x= 10

Step two:

so

Angle 1= 10+37= 47 °

Angle 2= 90= 90

angle 3= 10+67= 77 °

Here are the marks of a student in four exams. 65 80 76 69 The student takes a fifth exam. His mean mark for the five exams is 70 Work out his mark in the fifth exam

Answers

Answer:

mark of the fifth exam = 60

Step-by-step explanation:

Mean = sum of all marks / number of exam

Mean = 70

Number of exam = 5

Let x =

Mean = sum of all marks / number of exam

70 = (65 + 80 + 76 + 69 + x) / 5

Cross product

70 × 5 = (290 + x)

350 = 290 + x

350 - 290 = x

x = 60

mark of the fifth exam = 60

Can I get some help with this is the Last question

Answers

Answer:

x = 11

Step-by-step explanation:

Here, we want to get the value of x

Let’s start by looking at the point U

Now, we can see angles on a straight line at that point

Mathematically, angles on a straight line are supplementary

What this mean is that they add up to 180

Now, the value of the angle that falls into the triangle on that straight line will be;

180-(11x + 12)

Now, we have all the angles of the triangle

Mathematically, the sum of all is 180 as the a sum of the angles of a triangle is 180

5x + 10 + 58 + 180-(11x+2 )= 180

5x + 10 + 58 -11x-2 = 0

-6x+ 66 = 0

6x = 66

x = 66/6

x = 11

A line passes through the points (8, 8) and (4, 0). What is its equation in slope-intercept form?

Answers

Answer: y=2(x)-8

Explanation: (8,8) 8-4 and 8-0
- (4,0)- 4 8
- you take the 8 as the numerator and 4 and the denominator and then divide 8 by 4 to=2 which is your slope
- you pick 1 set of points (I chose (8,8) to finish the problem)
8(y-intercept)= 2(slope) • 8(x-intercept) +b
8= 16+b
-16 -16 (subtract 16 from both sides)
-8 (8-16) =b {b=-8)
-now you put together your equation,
which leaves you with { y=2(x) - 8}
^ ^
your slope your B value

The equation 4x + 2 has a domain of {0,3,6), what is the range

Answers

ExplanationDomain and Range

Domain is basically an input while Range is an output. Domain is the set of all x-values while Range is the set of y-values.

[tex]\large \boxed {domain} = > \large \boxed{range}[/tex]

From input to output. That means from if we substitute domain in the equation, we would get range.

Substitute x = 0,3 and 6 in the equation.

[tex]f(x) = 4x + 2 \\ f(0) = 4(0) + 2 = 0 + 2 = 2 \\ f(3) = 4(3) + 2 = 12 + 2 = 14 \\ f(6) = 4(6) + 2 = 24 + 2 = 26[/tex]

In quadrilateral PQRS, the exterior angle at Q measures 155 and PS = QR. What measure of ∠PSR would confirm that PQRS is a parallelogram?

Answers

Answer:

The measure confirming that PQRS would be 25

Step-by-step explanation:

It's easier if you draw it down.

1. We need to make this shape a parallelogram and the way we will do that is by making angle Q and angle S the same, because in parallelograms those opposite angles are required to be the same.  

                             \

                        155 \

P \ -------------------------\ Q

    \                         25 \

      \                               \     so that's your shape  

   S   \______________\ R

2.We were given that the exterior angle of Q measures 155, and since exterior and interior angles combined make 180, then we can assume that the interior angle of Q is 25.

3. As mentioned before, in a parallelogram, opposite angles are the same and  therefore PSR (which is just asking for the middle letter, S) is equal to 25 because Q is also 25.

Tell whether the triangle is right or not

Answers

Answer: Solved below...

Answer: Yes, that is a right triangle.

Step-by-step explanation:

To tell whether this is a right triangle or not you use a^2 + b^2= c^2

c is the hypotenuse the hypotenuse is the longest side of a right triangle, opposite the right angle. A and B can be either of the triangles sides.

To get this answer: 80^2+39^2 = 89^2

6400 + 1521 = 7921

7921=7921  

Since they are the same this IS a right triangle. Here is a little help for if the a question asks if you have a right acute or obtuse. To tell if you have an acute triangle the sign will be a greater than sign for ex) 180 > 169. If you have a obtuse triangle the sign would be a less than sign for ex) 120 < 200.

Here is a problem like that if you do not understand:

6^2 +12^2 = 13^2 ( remember c is the hypotenuse)

36+144= 169

180 > 169

A piece of wood is 0.9 metres long.
It is cut into three unequal pieces.
The first piece is 0.2 metres longer than the second piece.
The third piece is 23 hundredths of a metre shorter than the second piece.
How long is each piece of wood?

Answers

Answer:

The length of the first piece is 0.51 m

The length of the second piece is 0.31 m

The length of the third piece is 0.28 m

Step-by-step explanation:

The question is a simultaneous equation with word problem

The total length of the wood = 0.9 m

The number of pieces the wood is cut into = 3

The length of the first piece = 0.2 m + The length of the second piece

The length of the third piece = The length of the second piece - 0.23 m

Let "y" represent the length of the second piece, let "x" represent the length of the first piece, and let "z" represent the length of the third piece, we have;

x = 0.2 + y...(1)

z = y - 0.23...(2)

x + y + z = 0.9...(3)

Therefore, by substitution, we have;

0.2 + y + y + y - 0.23 = 0.9

3·y - 0.03 = 0.9

3·y = 0.9 + 0.03 = 0.93

y = 0.93/3 = 0.31

y = 0.31

The length of the second piece = y = 0.31 m

From equation (1), we have;

x = 0.2 + y = 0.2 + 0.31 = 0.51

x = 0.51

The length of the first piece = x = 0.51 m

From equation (2), we have;

z = y - 0.23

z = 0.51 - 0.23 = 0.28

z = 0.28

The length of the third piece = z = 0.28 m.
