Question

Redraw the figure and find the unknown angles with
proper reason.

​

Answer 1

Answer:

angle b =45 degree(alternate angles)

angle c=75 degree(alternate angles)

angle a=45+75+a=180 degree(as all the angles are occurring on the same line so the sum of all the angles are 180 degree)

120+a=180

a=180-120

a=60 degree

so,a=60 degree

b=45 degree

c=75 degree
