Part A: What trigonometric relationship (sine, cosine, tangent) would be used to determine the height of the
bird's nest?

Part B: Write an equation to determine the height of the bird's nest above the ground.

Part C: What is the height of the bird's nest above the ground?

Answer 1

tan 36 = opp /adj. opp is the height and adj is 14 ft

Height of bird nest

tan 36 = height / 14
14 tan 36 = height but this is height above Juans eyes....so we must add 5 ft to get to the true height above the ground

14 tan 36 +5 = height
