Answer 1

Answer:

1st figure...

Since equal sides has equal angles opposite to them.. therefore the third angle will also become x..

So,

x+x+80=180(Sum of angle property)

2x=100

x=50

2nd figure,

Angle on a straight line, 180-130 =50

Therefore other angle will also become 50 due to equal sides..

So,

x+50+50=180

x=180-100

x=80
