Below are sample questions representative of the exercises included on this worksheet and related GEO.95 Trigonometric ratios in right triangles skill assessments:

Problem 1Difficulty: Mastery
A right triangle has hypotenuse 41 and one leg 9. Angle theta is opposite the 9-unit leg. What is theta to the nearest tenth of a degree?
A12.7 degrees
B22.0 degrees
C77.3 degrees
D83.7 degrees
Solution & Explanation:For angle theta, the opposite side is 9 and the hypotenuse is 41. Use sine: sin theta = 9/41, so theta = sin^-1(9/41), about 12.7 degrees.
Problem 2Difficulty: Mastery
From a point 40 meters from the base of a tower, the angle of elevation to the top is 65 degrees. Which statement is correct?
AThe tower height is about 85.8 m because tan 65 = height/40.
BThe tower height is about 18.6 m because tan 65 = 40/height.
CThe tower height is about 36.3 m because cos 65 = height/40.
DThe tower height is about 94.6 m because sin 65 = height/40.
Solution & Explanation:The tower height is opposite the 65-degree angle and the ground distance is adjacent. tan 65 = height/40, so height = 40tan 65, about 85.8 m.
Problem 3Difficulty: Mastery
A rescue rope from a cliff top to a boat is 150 meters long. The angle of depression from the cliff top to the boat is 12 degrees. What is the vertical drop from the cliff top to the boat level, to the nearest tenth?
A31.2 m
B33.4 m
C146.7 m
D721.2 m
Solution & Explanation:The angle of depression is measured from a horizontal line. The vertical drop is opposite the 12-degree angle, and the rope is the hypotenuse. drop = 150sin 12, about 31.2 m.
