Given:

∠d and ∠e are complementary angles.

m∠d=5x+3 and m∠e=3x-1

To find:

The value of x.

Solution:

If two two angles are complementary angles, them there sum is 90 degrees.

$m\angle d+m\angle e=90^\circ$ (Complementary angles)

$(5x+3)^\circ+(3x-1)^\circ=90^\circ$

8x+2=90

8x=90-2

8x=88

Divide both sides by 8.

x=11

Therefore, the value of x is 11.
