Give "the angle" a variable, x.



Review that system and be sure you understand it. y is the complement of x and w is the supplement of x. The equation using only the y and w is for the last part of the description.


Understood? If no, keep examening until you do; if yes, then: Solve the system.

If half of the complement of a certain angle is 1° more than one-sixth of the supplement of the angle, find the angle.
Let angle be A

Then its complement is 90 - A, and its supplement is 180 - A

We then get: 



3(90 - A) = 180 - A + 6 ------ Multiplying by LCD, 6

270 - 3A = 186 - A

- 3A + A = 186 - 270

- 2A = - 84

A, or measure of angle = 

It's that easy....nothing COMPLEX!!
