Answer:



QRS is isosceles
Step-by-step explanation:
Given
See attachment for complete question
From the attachment, we have the following parameters





Solving further, we have:








From the calculations;

<em>This means that: QRS is isosceles</em>
B) X+4y=7
It works with both equations
Answer:
No; they do not have congruent corresponding angles.
Step-by-step explanation:
Angle U is ...
180° -28° -70° = 82°
The "corresponding" angle in ΔVWX is ∠X = 92°. These are not congruent, so the triangles cannot be similar.
