Question

Use the image to answer the question.

A right triangle upper A upper B upper C. The right angle, labeled upper C, is on the bottom left. The hypotenuse, side upper B upper A, slopes downward from top left to bottom right. Side upper A upper C is labeled 25. Side upper C upper B is labeled 20.

Use the inverse of the tangent ratio to find the approximate angle measure at vertex A
. Round your answer to the nearest whole degree.

Answer 1

tan(A) = opposite/adjacent = 20/25 = 0.8, so A = arctan(0.8) ≈ 38.66° ≈ 39°.
