Answer:
x=7
Step-by-step explanation:
Since these angles are complementary, they will add up to 90 degrees, so you can set up the equation like so:
8x+5+3x+8=90
First, combine like terms:
(8x+3x)+(5+8)=90
11x+13=90
Then, subtract 13 from both sides:
11x+13(-13)=90(-13)
11x=77
Then divide both sides by 11:
11x(/11)=77(/11)
x=7
7 is your answer
