Question

If m∠QOS=51​, m∠POR=59​, and m∠POQ=25​, what is m∠​ROS?

Answer 1

Pop es igual a 95 y ros es 55

Answer 2

∠ROS = 19

Explanation:

The angle sum theorem is applicable.

∠POQ + ∠QOR = ∠POR

∠QOR = ∠POR - ∠POQ . . . . . subtract ∠POQ

__

∠QOR +∠ROS = ∠QOS

∠ROS = ∠QOS - ∠QOR . . . . . subtract ∠QOR

∠ROS = ∠QOS - (∠POR - ∠POQ) . . . . . substitute for ∠QOR

∠ROS = ∠QOS - ∠POR + ∠POQ = 58 -61 +22

∠ROS = 19
