A + B = 180
A - B = 70
therefore:
A = B + 70
(B + 70) + B = 180 by substitution
2B = 110
B = 55
A = 180 - 55
B is smallest angle at 55 degrees
Hello from MrBillDoesMath!
Answer:
4 Pi
Discussion:
72/360 = 1/5 so the length of the arc is (1/5) the circumference or
(1/5) ( 2 Pi * 10) => C = 2 Pi r
(20/5) Pi =
4 Pi
