Answer:
<2 = 37.5 degrees
Step-by-step explanation:
Complementary angles add together to equal 90 degrees.
Let < 1 = x and < 2 = y
x + y= 90
x = y+15
Substitute the second equation into the first equation.
(y + 15) + y = 90
Combine like terms
2 y + 15 = 90
Subtract 15 from each side.
2y+15-15 = 90-15
2y =75
Divide each side by 2
2y/2 = 75/2
y = 37.5
<2 = 37.5 degrees
