Estimate: √116
a. 8
b. 9
c. 10
d. 11

D. 11

Hope This Is Sufficient

It's close to 11, as 11 squared = 121 and 10 squared=100. 116 is closer to 121 so I'd go for 11

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

221,500 is the answer
