Question

In the given figure, if ZRPS = 25°, the value of ZROS is ______ 

 

विकल्प

• 135°

• 145°

• 165°

• 155°

Answer 1

In the given figure, if ZRPS = 25°, the value of ZROS is 155°.

Explanation:

Since OR ⊥ PR and OS ⊥ PS
∴ ∠ORP = ∠OSP = 90°
In `square`ORPS, ∠ROS + ∠ORP + ∠RPS + ∠OSP = 360°
∠ROS + 90° + 25° + 90° = 360°
∠ROS = 360° - 205° = 155°
