Question

AB II CD, angle PQR ka maap kya hai
(a) (110⁰)
(b) (70⁰)
(c) (10⁰)
(d) (20⁰)​

Answer 1

Answer:

70°

Step-by-step explanation:

Given that :

• Angle APQ = 30°
• Angle CRQ = 40°

Since AB and CD are straight lines and parallel to each other ,

Extend the line PQ as it touches the line segment CD at S.

Then Angle PSR will be 30° [as angle PQR is 30 °]

Now , considering the triangle QSR ,

Angle QSR = 30° and QRS = 40° .

We also know that "Sum of the interior angles of a triangle is equal to the exterior angle, when the line is extended".

So angle PQR = 30° + 40° = 70°

The angle PQR is 70°
