Given that ∠MQL = 180° and ∠XQR = 180°, which equation could be used to solve problems involving the relationships between ∠XQL and ∠MQR?

Answer 1

The sum of the angles in a triangle is 180°. Therefore, we can use the equation:

∠XQL + ∠MQR + ∠XQR = 180°

Since ∠XQR = 180°, we can simplify the equation to:

∠XQL + ∠MQR = 0°

or

∠XQL = -∠MQR

This equation can be used to solve problems involving the relationships between ∠XQL and ∠MQR.
