Answer:
36°
Step-by-step explanation:
The computation of the measure of the angle is shown below:
As we know that
The trigonometric function in the right angle is
sinα = OS ÷ H
And,
cosα = AS ÷ H
Here
α represent the one of the angles
OS and AS represent the opposite sides
And, H represent the hypotenuse
So
sinx = 8.5 ÷ 14.5
x = arcsin = 8.5 ÷ 14.5
= 35.88
= 36 degrees
