Based on the figure below, what is the value of x? (5 points) select one: a. 1 b. 9 c. 11 d. 15

Note that when the two angles are combined, they form 90°

Solve for x.

5x + 15 + 20 = 90

Simplify. Combine like terms

5x + 35 = 90

Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

Subtract 35 from both sides

5x + 35 (-35) = 90 (-35)

5x = 55

Divide 5 from both sides

5x/5 = 55/5

x = 55/5

x = 11

c. 11 is your answer

hope this helps
