find x

Answer 1

`we \: know \: that \: \\ sumof \: ngles \: of \: a \: triangle = 180 \\ 8x - 4 + 6x + 2 + 9x - 2 = 180 \\ 8x + 6x + 9x - 4 + 2 - 2 = 180 \\ 23x - 4 = 180 \\ 23x = 184 \\ x = 184 / 23 \\ x = 8`

Answer 2

x= 8

Explanation:

All interior angles of a triangle equal 180 degrees.

Write it out as an equation:

180= 8x-4 + 6x+2 + 9x-2

Simplify:

180= 23x-4

Add four to both sides.

184= 23x

Then divide both sides by 23 and get 8 = x
