Question

DFG and JKL are complementary angles. m DFG= x+5, and m JKL=X-9. find the measure of each angle.

Answer 1

complementary means that the angles add up to 90..

x+5 + x- 9 = 90

2x - 4= 90
94=2x
x= 47

Answer 2

now plug in x to both of the angles equations and theres your answer

Answer 3

set them equal 90 degrees because complementary means they form 90 degrees.

x + 5 + x - 9 = 90

2x - 4 = 90

+4 +4
---- -----
2x = 90
