Question 417465: two angles are supplementary and one is 90 degrees more than twice the number . find the measures of the angles
x+(2x+90)=180
3x+ 90=180
-90 -90
3x= 90
x = 30

Hi

one is 90 degrees more than twice the (other?, believe was meant) 

Let x and (2x+90°) represent

Question states***

 x+(2x+90°)=180°   |Yes

Solving for x

    x = 30°        |Yes

 the complementary Angels are 30° and 150°  (2*30°+90°)



CHECKING our Answer***

   30° + 150° = 180°
