Question

What is the value of x?

Answer 1

x = 10

Explanation:

We know: the sum of the measures of triangle angles is 180°.

Therefore we have the equation:

`(6x-5)+5x+75=180` combine like terms

`(6x+5x)+(-5+75)=180`

`11x+70=180` subtract 70 from both sides

`11x=110` divide both sides by 11

`x=10`
