Answer:
The angles are 24 , 66
Step-by-step explanation:
If sum of two angles are 90, then they are complementary angles
m∠K + m∠L = 90
3x + 3 + 10x - 4 = 90
3x + 10x + 3 - 4 = 90 {Combine like terms}
13x - 1 = 90
Add 1 to both sides
13x = 90 + 1
13x = 91
Divide both sides by 13
x = 91/13
x = 7
m∠K = 3x + 3
= 3*7 + 3
= 21 + 3
= 24
m∠L = 10x - 4
= 10*7 - 4
= 70 - 4
m∠L = 66
