Question

Find the value of x in the following figures​

Answer 1

Step-by-step explanation:

Answer :a) OE make linear pair on

angle AOB +angle X = 180°

angle AOB = 120°. ( given)

120°+ X = 180°

X= 180°-120°

X = 60°

Answer : b) CO, OD and OE make linear pair on

.: angle AOC + COD + DOE + EOB = 180°

.: angle AOC = 45° ,angle COD = 65°

angle DOE = 20° and angle EOB = X

.: 45°+65°+20°+ X = 180°

130°+ X = 180°

X = 180°- 130°

X = 50°
