Question

Use the inverse of cosine to solve for the missing angle, rounded to the nearest whole degree.The hypotenuse of a right triangle is labeled 5 and the sides are labeled 3 and 4. The angle across from the side labeled 3 is labeled theta. A right angle symbol marks the right angle.

Answer 1

Adjacent = 4, hypotenuse = 5, so cosθ = 4/5.
θ = arccos(4/5) ≈ 36.87°, rounded ≈ 37°.
