Question

Find the value of x.5x55°O A. 11O B. 18O C. 25O D. 7Please help me

Answer 1

5x and 55 are complementary angles.

Complementary angles are two angles whose sum is exactly 90, therefore:

`\begin{gathered} 5x+55=90 \\ solve_{\text{ }}for_{\text{ }}x \\ 5x=90-55 \\ 5x=35 \\ x=(35)/(5) \\ x=7 \end{gathered}`
