Answer:
yes she is wrong
Step-by-step explanation:
becuse you add all of them up and get higher.
57+14=71 because if the difference is 57 71-57=14 so the difference is 14.
Since the angles sum of △ is 180°,here's the equation:
60°+65°+(8x+7)=180°
8x+7=180°-60°-65°
8x=55-7
x=48/8
x=6
Thus,the answer is x=6
Hope it helps!
