Answer:
17x² - 22x - 2
Step-by-step explanation:
Given
(5x² + 6x - 2) + 4x(3x - 7) ← distribute parenthesis
= 5x² + 6x - 2 + 12x² - 28x ← collect like terms
= 17x² - 22x - 2
I believe it would be 71 degrees because the total degrees of a triangle is 180 so 57+52=109 then 180-109=71 which would then be the final angle degree.
Hope I helped
