Respuesta :
Complementary angles are angles with a sum of ninety degrees.
We have already been given values for angle 1 and angle 2, so we can input them into an equation:
30 + 4x = 90
4x = 60
x = 15

Answer:
x=15
Step-by-step explanation:
Complementary angles add to 90 degrees
<1 + <2 = 90
30 + 4x = 90
Subtract 30 from each side
30-30 +4x = 90-30
4x = 60
Divide each side by 4
4x/4 = 60/4
x = 15
