Question

4x+5x= x=4x=5x=to gind the answer we are using complementary angles.

Answer 1

two complementary angles add up to 90

so

`4x+5x=90`

we can solve x

`\begin{gathered} 9x=90 \\ x=10 \end{gathered}`

and

`\begin{gathered} 4x=4(10) \\ =40 \end{gathered}`
`\begin{gathered} 5x=5(10) \\ =50 \end{gathered}`
