Question 871455
An angle measure (x+13) another angle complementary to it measure (2x+23) what's the value of x



-------------------------------------------------------



Complementary angles add to 90, so, 



(x+13)+(2x+23) = 90



x+13+2x+23 = 90



3x+36 = 90



3x = 90-36



3x = 54



x = 54/3



x = <font color="red">18</font>
