the sides and angles of a triangle are labeled. the adjacent side is labeled 9, the hypotenuse is labled 12 and the angle where the adjacent side and the hypotensue meet is labeled with the theta symbol the right angle is marked with a small box

use the inverse consine to find the missing angle round the answer to the nearest tenth

cos(θ) = adjacent/hypotenuse = 9/12 = 3/4
θ = arccos(3/4) ≈ 41.4°

So the missing angle is about 41.4°.
