Answer:
8 1/4
Step-by-step explanation:
8 because AB=BC as they are isosceles and 5/2.5=2 therefore ACx2=JL= 8
2/7 - 5/21 = 6/21 - 5/21 (find common denominator first, then subtract)
6/21 - 5/21 = 1/21
3/4 = 63/84
5/7 = 60/84
7/12 = 49/84
63/84 + 60/84+ 49/84 = 172/84
172/84 - 4/84 = 168/84
The answer is 168/84, or 2. Hope this helped!
