Answer:
DA is a straight line
so, 3x + 40 +18 + 64 = 180
3x= 180-122
x =58/3....
hence value of x is 58/3
putting value of x in ( 3x + 40)
angle DOE = 58/3×3 + 40
Angle DOE = 98⁰
➡️
x= 38
3x + 40 + 18 + 64 = 180
3x + 122 = 180
3x = 180 - 122 = 58
x = 58/3
44 + 2x + x + 20 = 180
3x + 66 = 180
3x = 180 - 66 = 114
x = 114/3 = 38
