Answer:

a = 50

b = 50

c = 80

d = 50

e = 130

Explanation:

e = 180 - (25 + 25) {Angle sum property & It is an isosceles triangle}

= 180 - 50 = 130

a +e = 180 {Linear pair}

a + 130 = 180

a = 180 - 130

a = 50

d =a {Vertically opposite angles}

d = 50

c = 180 -(50+ 50 ) {Angle sum property & It is an isosceles triangle}

c = 180 -100

c = 80

a+b + c = 180 {Straight angles}

50 + b + 80 = 180

b + 130 = 180

b = 180 - 130

b = 50
