Question

Plz answer this immediately.

Answer 1

Answer:

1) 40

2) x = 40 + 50

x = 90

3)a= 180-61 =119

b= 61+ 65= 126

c= 180 - 65=115

4) y = 180-92= 88

y+50+x = 180

x= 180 -(50+88)

= 180 - 138

x =42

5) c+48+58= 180

c= 180 - 106

c=74

d = 180 - 58 =122

a = 180 - d = 180 - 122= 58

a+b+c= 180

58+ 74 +b =180

b= 180 - 132 =48

also I have used these formulas

sum of angles on straight line = 180

sum angles in a triangle = 180

sum of adjacent angles in a parallel line divided by a transverse = 180

external angle = sum of opp

interior angles
