90 - 40 = 50
Complementary angles add up to 90 degrees.
If one angle is 40 degrees less than the other, you just put it into an equation where 40 is subtracted from 90.
The answer would then be 50 degrees.

Answer:
MARK AS BRAINLIST
Step-by-step explanation:
w=5 L=7
w=5+x. L=7+x
A = w*L
= (5+x)* (7+x)
=35+5x+7x+x^2
=x^2+12x+35
Cross multiply
15/18 = x/100
100 • 15/ 18 = x
x = 83.333333 %
