Question

In the figure,if AB||CD, angle ABP=30° and angleCDP=40° find the x ​

Answer 1

Explanation:

Given,

Angle ABP=30

Angle CDP=40

let us suppose,we draw AB perpendicular BC from point Q to R

Now, In triangle PQR,

angleQPR +Angle PRQ +Angle PQR =180

or,x + 90-40 + 90-30 =180

or,x=70

hence angle QPR is 70
