Answer:
51.3 degrees
Step-by-step explanation:
You use the tangent function. You know that tangent of an angle, y, is opposite/adjacent. Set up an equation:
tan(y) = 10/8
You use the inverse tangent (NOT COTANGENT) function, and you get:
y = tan^-1 (10/8)
Type this in your calculator, and you get 51.3 degrees.
