Question

find x in the following figures:​

Answer 1

Answer:

11.33 question ki answer 70

Step-by-step explanation:

the sum of interior angles are 180

let the 2 and 3 angles are 2x

2x + 40 = 180

2x = 180 -40

2x = 140

x = 140 ÷ 2

x = 70

Answer 2

Answer:

fig 11.33 : x = 88°

fig 11.34 : x = 130°

explanation

fig 11.33

AB || DC

therefore, angle BAD = angle ADC

=> angle ADC or angle EDC = 52°

now in triangle DCE, by angle sum property,

E+D+C = 180°

x + 52° + 40° = 180°

x = 180-92

x = 88°
