Suppose ;


the \: angle \: = \: x

Thus the supplementary of x is :


180 - x

_________________________________

x angle measures 4° more than its supplementary ;

So :


x - (180 - x) = 4


x - 180 + x = 4


2x - 180 = 4

Add sides 180


2x - 180 + 180 = 4 + 180


2x = 184

Divided sides by 2


(2)/(2)x = (184)/(2) \\


x = 92

Thus the angles measures

are : 92° and 88°

DONE....
