Answer:
x = 14
Step-by-step explanation:
Two angles a, b are complentary if a+b = 90.
Therefore, 4x + (2x+6) = 90
6x + 6 = 90
6x = 84
x = 84/6 = 14.
x=14°
Complementary angles are angles that add to 90°.
4x+2x+6=90
add like terms
6x+6=90
subtract 6 on both sides
6x=84
divide 6 on both sides
x=14
x is 14°.
