Question

find the angles in each of the following number one the angles are adjacent and form an angle of 140 degree .the smaller is 28 degree less than the larger

Answer 1

let the larger angle be x

smaller angle be x - 28

given sum of angle is = 140

x + x - 28 = 140

2x - 28 = 140

2x = 140 + 28

2x = 168

x = 168/2

x = 84

larger angle is 84

smaller angle is x - 28 = 84 - 28 = 56
