Question

(Day 8) Find the value of each variable. The dot represents

the center.


a =
b=
C=​

Answer 1

Explanation:

a=180-122=58°

Let ABC be the triangle in which BC is diameter.

Diameter always make angle 90° on the circumference.

so b=90°

∠B=1/2×58=29°

29+b+c=180

29+90+c=180

c=180-119=61°
