Question

In angle MNS, MN=MS If angle M =80 degree what is angle N​

Answer 1

Answer :-

》 since MN = MS

ANGLE N = ANGLE S

》 ANGLE M + ANGLE N + ANGLE S = 180

》 ANGLE N = (180 - 80 )/2 = 100/2 = 50

Answer 2

Answer:

angle MNS = 180°

angle M=80°

angle N=S=2x

MNS=M+N+S

180°=80°+ 2x

180°-80°=2x

100°=2x

2x=100°

x=100°/2

x=50°
