Class 10 Maths1)The distance between two parallel tangents of acircle of radius 4 cm is
8cm
Class 10 Maths2)In the given figure, if ZRPS = 25°, the value of ZROS is
155°
Since OR ⊥ PR and OS ⊥ PS
∴ ∠ORP = ∠OSP = 90°
In □ ORPS, ∠ROS + ∠ORP + ∠RPS + ∠OSP = 360°
∠ROS + 90° + 25° + 90° = 360°
∠ROS = 360° – 205° = 155°
