Question

the image of trapezoid pqrs after a reflection across wy is trapezoid pqrs. what is m∠yxs? 45° 90° 180° 270°

Explanation:

Step1: Recall the property of a straight - line angle

A straight - line forms an angle of 180°. The points W, X, and Y are collinear, and ∠YXS and ∠WXS form a straight - line.

Step2: Determine the measure of ∠YXS

Since ∠WXS + ∠YXS=180° and ∠WXS is a straight - line angle, and we know that a straight - line angle has a measure of 180°. If we assume that the line WXY is a straight line, then ∠YXS = 180°.

Answer:

180°
