Step-by-step 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
