a triangle...
Angle 1 is 20 degrees, angle 2 is 90 and angle 3 is unknown.
Side C is 10 feet, the other two sides are x and y.
Solve for x and y.
:
Sin(20) = 10%2Fx; (side opposite/hypotenuse)
.342x = 10
x = 10/.342
x = 29.238 ft
:
Tan(20) = 10%2Fy; (side opposite/side adjacent
.364y = 10
y = 10/.364 ft
y = 27.475
