Answer:
m∠SRZ=40°
Step-by-step explanation:
The figure shows rectangle RSTW which has the angle RTW with measure of 40°.
1. Sides SR and TW are parallel as opposite sides of rectangle, then angles SRZ and RTW are alternate interior angles. By alternate interior angles theorem, they are cingruent, so m∠SRZ=40° . This option is true.
2. Angles STZ and RTW aro complementary (add up to 90°), then
m∠STZ=90°-40°=50°. This option is false.
3. Angle SRW is a right angle (in rectangle all angles are right angles). By the definition of right angle,
m∠SRW=90°. This option is false.
4. Angle TWR is a right angle (in rectangle all angles are right angles). By the definition of right angle,
m∠TWR=90°. This option is false.
