Answer:
Explanation:
the little top blurb says ∠E + ∠F = 120
so
7x+2 + 8x -2 = 120
15x = 120
X = 8
since we know that all the angles of the triangle will add up to 180, we know G will be 60°
B) will make 60 if we plug in our answer of 8 :)
7x + 4
7x + 2 + 8x - 2 = 120
7x + 8x = 120
120 ÷ 15 = 8
7(8) = 56 + 4 = 60
60 + 120 = 180
