Question

Find θ. Round to the nearest degree. Right Triangle Trigonometry.

Answer 1

≅ 64°

Explanation:

using rule of cos invers

`Cos^(-1) ((7)/(16) )=64.05\\`

Answer 2

64 =theta

Explanation:

We have a right triangle.

We know the adjacent side and the hypotenuse

adjacent/ hypotenuse = cos theta

7/16 = cos theta

Take the inverse cos of each side

cos ^-1 ( 7/16) = cos ^ -1 cos theta

64.05552023 = theta

64 =theta
