Question

look at this diagram: if oq and rt are parallel lines and m∠qps = 128°, what is m∠tsu?

Explanation:

Step1: Identify angle - relationship

$\angle QPS$ and $\angle TSU$ are corresponding angles.

Step2: Apply property of corresponding angles

For parallel lines $OQ$ and $RT$, corresponding angles are equal. Since $m\angle QPS = 128^{\circ}$, then $m\angle TSU=m\angle QPS$.

Answer:

$128$
