The larger of two supplementary angles exceeds 7 times the smaller by 4 degrees. Find the measure of the larger angle. 

 

I can't figure this out please help ;-;

Let x be the smaller angle....and we have that...

 

x + (7x + 4)  = 180   simplify

 

8x + 4  =  180     subtract 4 from both sides

 

8x = 176    divide both sides by 8

 

x = 22°  = the smaller angle

 

7(22°) + 4   =  158°  = the larger angle
