Question

The following figures are not drawn to scale but

AB and CD (if present in the picture) are straight lines. Find x:

Answer 1

Answer :

x = 2.5

Explanation:

Given

AB and CD are straight lines.

So the angles 170 and 4x form linear angle.

The sum of linear angles is 180 deg. So we can write:

170 + 4x = 180

4x = 180 - 170

4x = 10

x = 10/4

x = 2.5

The value is x = 2.5
