Question

Solve for a and b in the following circles:
B)
a а
b
82°

Answer 1

a 41

when the line touch the circle you have to take the half of it

for b its equal 144

the full circle degree is 360

so we can say the 82+2x=360

because the two lines in the circle equal each other so its means tha the Piece of the circle in the left is equal b too

hopefully its helpful and sorry because of my engilish
