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.

Answer 1

tan(B) = opposite/adjacent = 25/20 = 1.25, so B = arctan(1.25) ≈ 51.34°.

Rounded to the nearest degree: 51°.
