Answer:
42
Step-by-step explanation:
Angle ABD = Angle CBD + Angle ABC
You know ABD is 70, CBD and ABC are in terms of x
70 = 5x + 13 + 3x + 33
70 - 13 - 33 = 8x
24 = 8x
3 = x
Replacing x in Angle ABC:
3 * 3 + 33 = 42
You use the formula C=2(3.14)r r is the radius and in this situation 2 so the answer will be 12.56
The answer is B. 100/5=20 hope i helped
