Question

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

Answer 1

Answer:

(I) 60 + x = 180

x = 180 - 60 = 120

(II) 3x + 2x = 180

5x = 180

x = 180/5 = 36

(iii) 35 + x + 60 = 180

95 + x = 180

x = 180 - 95 = 85

iv) 83 + 92 + 75 + 47 + x = 360

297 + x = 360

x = 360 - 297 = 63

v) 3x + 2x + x + 2x = 360

8x = 360

x = 360/8 = 45

vi) 105 = 3x ( opposite angles r equal)

105/3 = x

35 = x
