Question

I need help approaching 5 and 6 i onto understand it

Answer 1

Angle A and angle X are congruent because the triangles are similar.

`6x-4=2x+28`

Then, we solve for x.

`\begin{gathered} 6x-2x=28+4 \\ 4x=32 \\ x=(32)/(4) \\ x=8 \end{gathered}`

We use this value to find angle C.

`m\angle C=4x+17=4(8)+16=32+17=49`

Therefore, angle C measures 49°.
