Question

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

(1 point)
The approximate measure of angle B
𝐵
is °.

\[ B = \tan\^{-1}\left(\frac{25}{20}\right) \]

The answer is not 39.

Answer 1

First compute the ratio: 25/20 = 1.25.
Then B = arctan(1.25) ≈ 51.34°, so rounded to the nearest degree B ≈ 51°.
