Special Right Triangles

Answers

Answer 1

Answer:

first option

Step-by-step explanation:

Using the sine/ cosine ratios in the right triangle and the exact values

sin30° = [tex]\frac{1}{2}[/tex] , cos30° = [tex]\frac{\sqrt{3} }{2}[/tex]

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{32}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2x = 32 ( divide both sides by 2 )

x = 16

----------------------------------------------------------

cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{y}{32}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2y = 32[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

y = 16[tex]\sqrt{3}[/tex]

How to use substitution to solve

Answers

Given:

A. Evaluate [tex]\dfrac{3}{8}x-4.5[/tex] when x=0.04.

B. Evaluate [tex]8.4n-3.2p[/tex] when n=2 and p=4.

To find:

The values of the given expression at the given values.

Solution:

A.

We have,

[tex]\dfrac{3}{8}x-4.5[/tex]

Putting x=0.04 in the above expression, we get

[tex]\dfrac{3}{8}(0.04)-4.5[/tex]

[tex]=0.015-4.5[/tex]

[tex]=-4.485[/tex]

Therefore, the value of the expression at x=0.04 is -4.485.

B.

We have,

[tex]8.4n-3.2p[/tex]

Putting n=2 and p=4 in the above expression, we get

[tex]8.4(2)-3.2(4)[/tex]

[tex]=16.8-12.8[/tex]

[tex]=4[/tex]

Therefore, the value of the expression at n=2 and p=4 is 4.

which set of vaules could be the side lengths of a 30-60-90 triangle

Answers

Answer:A 30-60-90 right triangle is a special right triangle in which one angle measures 30 degrees and the other 60 degrees. The key characteristic of a 30-60-90 right triangle is that its angles have measures of 30 degrees (π/6 rads), 60 degrees (π/3 rads) and 90 degrees (π/2 rads). The sides of a 30-60-90 right triangle lie in the ratio 1:√3:2.

Step-by-step explanation:

The side lengths of a 30-60-90 triangle can be expressed as x, x√3, and 2x, where x is a positive constant.

We have,

In a 30-60-90 triangle, the angles measure 30 degrees, 60 degrees, and 90 degrees.

The side lengths of a 30-60-90 triangle have a specific ratio.

Let's denote the length of the shortest side as x, the length of the side opposite the 60-degree angle as y, and the length of the hypotenuse as z.

The ratios of the side lengths in a 30-60-90 triangle are as follows:

Shortest side: x

Side opposite 60-degree angle: y = x√3

Hypotenuse: z = 2x

Given this ratio, we can determine which set of values could be the side lengths of a 30-60-90 triangle.

The values must satisfy the above relationships.

Possible sets of values for the side lengths of a 30-60-90 triangle are:

Set 1:

x = 1

y = x√3 = √3

z = 2x = 2

Set 2:

x = 2

y = x√3 = 2√3

z = 2x = 4

Set 3:

x = 3

y = x√3 = 3√3

z = 2x = 6

Set 4:

x = k (where k is any positive constant)

y = x√3 = k√3

z = 2x = 2k

These sets of values satisfy the ratios for a 30-60-90 triangle.

Remember that the ratios are consistent, so any positive constant can be chosen for the length of the shortest side (x), and the other side lengths (y and z) will follow accordingly.

So,

Any set of values that satisfy the ratios given above could be the side lengths of a 30-60-90 triangle.

Thus,

The side lengths of a 30-60-90 triangle can be expressed as x, x√3, and 2x, where x is a positive constant.

Serenity has some pennies and some nickels. She has no less than 18 coins worth at most $0.66 combined. If Serenity has 12 pennies, determine the maximum number of nickels that she could have. If there are no possible solutions, submit an empty answer.

Answers

Answer: 10 nickels

Step-by-step explanation:

A pennie is a cent or $0.01. Serenity has 12 pennies so the amount she has from pennies is:

= 12 * 0.01

= $0.12

The amount she has in nickels at most is therefore:

= 0.66 - 0.12

= $0.54

A nickel is $0.05 so the number of nickels are:

= 0.54/0.05

=  10.8 nickels

= 10 nickels

If she has 10 nickels then the total she would have is:

= (12 * 0.01) + (10 * 0.05)

= $0.62

This fits the parameters

The scatter plot shows the number of passengers at a major airport over a​ 15-year period from the year 2000. About how many passengers traveled through this airport in the year​ 2011?

Answers

Answer:

The answer is 65

Step-by-step explanation:

​First, determine the​ x-value that corresponds to the given year.

Since x corresponds to the number of years since​ 2000, the year 2009 corresponds to an​ x-value of 9.

​Next, find the​ y-value on the trend line that corresponds to an​ x-value of 9. The problem statement has been updated to show lines traced from the​ x-value of 9 to the trend line and then to the​ y-value.

Notice that the point​ (9,70) appears to lie on the trend line.

​Therefore, in​ 2009, approximately 70 million passengers travelled through the airport.

PRD and BPR are same side interior meaning they are supplementary so

BPR=70 and APB is a straight line meaning it = 180 which gives you

64+70+x=180

The measure of angle x is 50 degrees.

What are supplementary angles?

Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two two angles are two pairs of supplementary angles.

We can see that Angle BPR and angle PRD are supplementary angles, thus their sum is equal to 180

Angle BPR + 115 = 180

Now subtract 115 from both sides;

BPR = 65

Also, the angles APQ, x, and BPR form a straight line and their sum is equal to 180

65 + x + 65 = 180

Now add like terms;

130 + x = 180

x = 50
