Question

Can u please help me find the value of each variable?

Answer 1

The arc measure, which corresponds to the central angle measure, is always twice the subtended angle.

So 60 is twice a,

Answer: a=30

84 is twice b

Answer: b=42

60 + 100 is twice c,

Answer: c=80

d is what's left of the circle, total 360 degrees,

d = 360 - 84 - 60 - 100 = 116

Answer: d=116
