Complementary angles = 90°
x= angle 1
(90-x)= angle 2
Subtract the two angles to get the difference between them (18°).
(90-x) - x= 18
combine like terms
90 - 2x= 18
subtract 90 from both sides
-2x= -72
divide both sides by -2
x= 36° angle 1
Substitute answer in to find angle 2:
=90 - x
=90 - 36
=54° angle 2
Hope this helps! :)
The sides could be 10.2 inches or 15.7 inches.

13x - 7
You get this answer by adding the two together because mWEV is equivalent to the two known angles put together.
Hope this helps!
The answer is C. Good luck
