Answer 2

Use the image below to answer the following question.
What relationship do the ratios of sin x° and cos y° share?

The ratios are opposites (negative 7 over 25 and 7 over 25).

The ratios are reciprocals ( 7 over 25 and 25 over 7).

>>The ratios are both identical ( 7 over 25 and 7 over 25).

The ratios are both negative (negative 25 over 7 and negative 25 over 7).

Answer 3

The picture shows a barn door:

What is the distance BC between the two horizontal parallel bars?

4 by cos 45 degrees

4 sin 45°

4 by tan 45 degrees

>>4 tan 45°

Answer 4

What is the distance between the zoo and the library?

300 feet

>>600 feet

900 feet

100 feet

Answer 5

Look at the triangle:

What is the value of tan x°?

8 ÷ 6

6 ÷ 10

>>10 ÷ 6

8 ÷ 10

Answer 6

If the cos 30° = square root 3 over 2, then the sin 60° = _____.

0, because the angles are complementary

1 over 2, because the angles are complementary

>>square root 3 over 2, because the angles are complementary

1, because the angles are complementary

Answer 7

Two birds sit at the top of two different trees. The distance between the first bird and a bird watcher on the ground is 29.7 feet. The distance between the bird watcher and the second bird is 42.1 feet.

What is the angle measure, or angle of depression, between this bird and the bird watcher?

45.1°

>>44.9°

54.8°

35.2°

Answer 8

If tan x° = 3 divided by y and cos x° = y divided by z ,what is the value of sin x°?

>>sin x° = 3 divided by z

sin x° = 3y

sin x° = z divided by 3

sin x° = 3z
