Question 826405
Set x = the angle
Since x + ( complement of x ) = 90
(complement of x) = 90 - x

Translating the original quote,
x = 4(90-x) + 30
x = 360 -4x + 30
x = 390 -4x
add 4x to each side
5x = 390
divide each side by 5
 x = 78
(complement of x) = 90 - x = 90 - 78 = 12
The original angle is 78 and the complement is 12
