does anyone know the values of x and y? my teacher didn’t go over this type of problem

Answers

Answer 1

Answer:

x = 80

y = 100

Step-by-step explanation:

First, we need to figure out how many degrees there are in total in the inside of the polygon. There are 7 sides, so now let's use the formula to find out the total degrees.

(n - 2) * 180

"n" is the amount of sides.

(7 - 2) * 180 =

5 * 180 =

900

The total degrees is 900.

Now, we have to add all the sides in the inside to form an equation to solve for y.

y + 135 + 140 + 150 + 120 + 135 + 120 = 900

y + 800 = 900

y + 800 - 800 = 900 - 800

y = 100

Now, we know that x and y are supplementary angles. So the sum of x and y is 180. We can use that to create an equation to solve for x!

x + y = 180

x + 100 = 180

x + 100 - 100 = 180 - 100

x = 80

Therefore, x = 80 and y = 100

All right triangles are isosceles.
Which example proves this statement is false?

Answers

Answer:

Step-by-step explanation:

It is a 3-4-5 right triangle

The example Option B is False as it is a right triangle with base lengths 3 , 4 and 5

Hence , the example B is not an isosceles triangle

What Is an Isosceles Triangle?

A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.

The three types of Isosceles Triangles are :

Isosceles acute triangleIsosceles right triangleIsosceles obtuse triangle

Given data ,

From the figure Triangle A
In this Triangle , the two sides are of equal length and one side is different

So , the triangle is an isosceles triangle

From the figure Triangle B

In this triangle , all the three sides are different and it is also a right angled triangle with different lengths

So , the triangle is not isosceles

From the figure Triangle C
In this Triangle , the three sides are of equal length , so it is also an isosceles triangle

So , the triangle is an isosceles triangle

From the figure Triangle D
In this Triangle , the two sides are of equal length and one side is different

So , the triangle is an isosceles triangle

Hence , the example B is not an isosceles triangle and is FALSE

Can someone help solve this?

Answers

Answer:

x = 8

y = 18

Step-by-step explanation:

First, it would be easiest to start by drawing a picture. To do so, draw two simple Isosceles triangles. Then, label their points. One having the points F, U, and N while the other has B, A, and T. Now, since both triangles are congruent, that means that F≅B, U≅A, and N≅T. Because of this knowledge, FN would be congruent to BT. So, you would be able to write that 52 = 14x - 60. By solving that, you would get the answer to x. Moving onto y, you would see that since the triangles are congruent, the interior angles are too. So, you would be able to use angles F and N to find A. By adding them to 180°, the equation would look like: 71° + 36° + (3y + 19)° = 180°. So, you would be able to find the answer to y.

At the sandwich shop, there is a sale each afternoon. A customer has a choice of
three types of bread and five different meats. Use the Fundamental Counting
Principle to determine how many combinations a customer can create ?

Answers

Answer:

15 combinations

Step-by-step explanation:

The fundamental counting principle states that if there are p ways to do one thing, and q ways to do another thing, then there are p×q ways to do both things. This means we need to multiply 3 by 5 to get the possible amount of combinations. This gets us 15. This means there are 15 combinations of bread and meat.

Write the equation of the function g(x) if g(x) = f(x - 3) +1 and f(x) = x3 + 1.

Answers

Answer:

Solution,

f(x) = [tex]x^{3}[/tex] + 1

Put x = x - 3,

f(x - 3) = [tex](x-3)^{3}[/tex] + 1

Now,

g(x) = f(x - 3) + 1

or, g(x) =[ [tex](x-3)^{3}[/tex] +1 ] + 1

or, g(x) = [tex]x^{3} -9x^{2} + 27x - 1 + 1+1[/tex]

or, g(x) = [tex]x^{3} - 9x^{2} +27x + 1[/tex]

Step-by-step explanation:

The answer is C because both numbers in 4:9 can be multiplied by the same factor (3) to get 12:27, the answer. No other choice works because they require two different number factors, not just one, which means they aren't equivalent ratios to 4:9.
