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!
1 inch is 1/12 of a foot
3 inches is 1/4 of a foot
Number line would be divided into 12. The first spot would be 1/12, the next would be 2/12 and so on. Make a mark at 1/12 for one inch and at 3/12 for 3 inches
