Two angles are supplementary. One angle is 27 more than twice the other using x and y. Find each sides degree.

Sagot :

Answer:

By the question,

x + y = 180 - eqn i

x = 27 + 2y - eqn ii

Substituting eqn ii in eqn i,

27 + 2y + y = 180

or, 3y = 153

so, y = 51

x = 180 - 51 = 129

The angles are 129 and 51.
