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.

Angle B has tangent = opposite/adjacent = AC/CB = 25/20 = 1.25.
So B = arctan(1.25) ≈ 51.34°, which rounds to 51°.

The measure of angle B is 51°.
