<em>Answer:</em>
( B ) x = 6.5
<em>Step-by-step explanation:</em>
We know that all the angles of a triangle equal 180 when added together. So lets make an equation for this question.
(10x-10) + (10x+8) + 8x = 180
I just took all the angles and added them together to make 180. Now solve for x.
10x - 10 + 10x + 8 + 8x = 180 <em>(combined like terms)</em>
28x -2 = 180 <em>(added 2 to both sides)</em>
28x = 182 <em>(divided both sides by 28)</em>
x = 6.5
