Answer:

$\Huge\boxed{B.x=12}$

Explanation:

Hello There!

They have given us each measure of a triangle's angles

Remember all of the angles in a triangle add up to equal 180

so we can use this equation to solve for x

180 = 2x + 5 + 6x - 5 + 7x

step 1 combine like terms

2x+6x+7x=15x

5-5=0

now we have 180 = 15x

step 2 divide each side by 15

180/15=12

15x/15=x

we're left with x = 12
