Answer 1

Answer:

angle b= 70

angle c = 80 and

angle a = 30

Answer 2

Answer:

in the given triangle,

angle b will be equal to 70 degree (vertically opposite angles)

and angle c +100 degree = 180° (linear pairs)

angle c = 80°

in the given triangle,

a +b + c= 180° ( angle sum property of triangle)

a+70+80= 180

a= 180-150

a = 30°

therefore,

a= 30°

b= 70°

c= 80°
