Question

find the value of x in each of the following figures.​

Answer 1

Answer:

140°

Step-by-step explanation:

∠2 + 110° = 180° (Linear Pair)

∠2 = 70°

∠1 + 90° = 180° (Linear Pair)

∠1 = 90°

________________________

∠1 + ∠2 + 60° + x = 360° (Angle Sum Property)

90° + 70° + 60° + x = 360°

x = 140°

Answer 2

Answer:

x=140

Step-by-step explanation:

let the figure be quad . abcd

angle a = 60

angle b = x

angle c= 180 - 90

=90 ( supplementary angle)

angle d = 180-110

70(supplementary angle)

according to property of quad.

sum of angle of quad. = 360

60+x+90+70=360

x=360-(60+70+90)

x =360-220

x=140
