To find the indicated angle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from the angle, we know the adjacent side and the hypotenuse. Therefore, we should use cosine to solve.
cos(x) = 12/36
x = cos^-1(12/36)
x = 71 degrees
Hope this helps!
Slope = y1-y2/x1-x2 .. 5-3/-3--3 = math error (its parallel to y axis)
6 + 2y = x
x + y = 180°
6 + 2y + y = 180°
3y = 174
y = 58°
x = 180° - 58°
x = 122°
