Question

WAZ e Congruence K 2 of 1 I Right Triangles What is the value of x?

Answer 1

We have to use the interior angles theorem, which states that the interior angles in a triangle must sum 180°.

`\begin{gathered} 8x+x+90=180 \\ \end{gathered}`

Then, we solve for x

`\begin{gathered} 9x+90=180 \\ 9x=180-90 \\ 9x=90 \\ x=(90)/(9) \\ x=10 \end{gathered}`

Hence, x is equal to 10°.
