Answer» In the given triangleAngle x + 80 = 180 Linear pairAngle x = 180 - 80 = 100 Angle c + 120 = 180 Linear pairAngle c = 180-120 = 60 By angle sum property of triangle Angle c + Angle x + Angle y = 18060 + 100 + Angle y = 180Angle y = 180-160 = 20 Thus x = 100, y = 20

ASSIGNMENT 7.2MCQ) Chood1. Multiple Choice Questions CMo In the following figure, the valuesof x and y are respectively(a) 120Â°, 80 (b) 40, 100Â°(c) 100, 40 (d) 80, 12080120C xthe measures of some

Answer»

In the given triangleAngle x + 80 = 180 Linear pairAngle x = 180 - 80 = 100

Angle c + 120 = 180 Linear pairAngle c = 180-120 = 60

By angle sum property of triangle

Angle c + Angle x + Angle y = 18060 + 100 + Angle y = 180Angle y = 180-160 = 20

Thus x = 100, y = 20
