Question

find the measure ofan angle if its supplement measures 10 degrees more than three times its complement.

Answer 1

you get two equations from this:
1.) x + (10 + 3y) = 180, where x is your angle and y is the complement
2.) x + y = 90

Solving, y = 90 - x (Plug into 1)-->
x + (10 + 3(90 - x)) = x + 280 - 3x = 180-->
-2x = -100-->
x = 50 degrees

Answer 2

Wow, i missed the entire step! thank you
