Question

In the adjoining figure, ∆AOB is a straight line. If x=30,y=3x , find z

Answer 1

Answer:

Explanation:

x= 30

y = 3x

 = 3*30

 = 90

ATQ

AOB is a strait line

therefore

x + y + z =180             [STRAIT ANGLE]

30 + 90 + z = 180

120 + z = 180

z = 180 - 120

z  = 60

therefore z = 60
