Hii, can you please help me check this test? I've got most of the answers, but want to make sure they're correct. If you can't do all of them that's fine :) 1.
The figure below shows a right triangle:
A right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units. The angle b
What is p ÷ r equal to?

tan x°
tan y°
sin y°
cos x°

2.
Look at the figure below:
An image of a right triangle is shown with an angle labeled y degrees.
If sin y° = 9 divided by c and tan y° = 9 divided by d, what is the value of cos y°?

cos y° = 9c
cos y°= c divided by d
cos y°= d divided by c
cos y° = 9d

3.
The picture below shows a portion of a river dam:
A right angle triangle is shown with acute angle on base equal to 50 degrees and the length of base equal to 115 meters.
Which of the following can be used to calculate the height of the river dam?

115 divided by cos 50 degrees
115 cos 50°
115 tan 50°
115 divided by sin 50 degrees

4.
Which expression is equal to sec x° multiplied by cot x°?

hypotenuse ÷ adjacent
adjacent ÷ hypotenuse
opposite ÷ adjacent
hypotenuse ÷ opposite

5.
The sail of a boat is in the shape of a right triangle, as shown below:
The sail of a boat is a right triangle with an acute angle equal to 35 degrees and the side of the sail which is the hypotenuse
Which expression shows the height, in meters, of the sail?

8 divided by cosec 35 degrees
8 sin 35°
8 sec 35°
8 divided by sec 35 degrees

6.
Find the measure of angle x. Round your answer to the nearest hundredth. (please type the numerical answer only)
A right triangle is shown with one leg measuring 4 and the hypotenuse is labeled 5. An angle across from the leg measuring 4 is

7.
Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only)
A right triangle is shown with one leg measuring 4 and the hypotenuse is labeled 20. An angle across from the leg measuring 4

8.
If the sin 0° = 0, then which statement is true?

cos 90° = 1, because the cosine and sine are complements
cos 180° = 1, because the cosine and sine are supplements
cos 90° = 0, because the cosine and sine are complements
cos 180° = 0, because the cosine and sine are supplements

9.
The picture below shows a right-triangle-shaped charging stand for a gaming system:
The side face of a charging stand is a right triangle labeled ABC. The measure of angle ACB is 90 degrees and the measure of an
Which expression shows the length, BC, of the base of the stand?

7 divided by cot 55 degrees
7 cos 55°
7 divided by sin 55 degrees
7 cot 55°

Jim is designing a seesaw for a children's park. The seesaw should make an angle of 30° with the ground, and the maximum height to which it should rise is 2 meters, as shown below:
A see-saw is shown with one end on the ground and the other in the air. The see-saw makes an angle of 30 degrees with the ground
What is the maximum length of the seesaw?

3.00 meters
3.5 meter
4.00 meters
4.5 meters
