Answer:
(E) 90°
Step-by-step explanation:
The diagonals of a parallelogram are equal in length if and only if the parallelogram is a rectangle.
Any angle of a rectangle is 90°.
_____
Adjacent angles of a parallelogram are supplementary. If the diagonals are the same length, the triangles formed by either diagonal are congruent with the triangles formed by the other diagonal. This means adjacent angles are congruent. Congruent supplementary angles are 90°.

Answer:
SR and RZ
Step-by-step explanation:
A perpendicular bisector is a line segment that passes through the midpoint of a side of a triangle. In other words, If it goes through a side, it should split the segment in half perfectly. Furthermore, it must be perpendicular to the side it passes through (it should form a ninety-degree angle with the side). Given these two rules, one can say that one of the perpendicular bisectors is SR. SR forms a right angle with (and is thus perpendicular to) side AB. Furthermore, AS is congruent to (has the same length as) SB, which means SR cuts AB in half exactly. Another bisector would be RZ (for similar reasoning). Let me know if that doesn't make sense.

Answer:
Dimensions of rectangle = <u>23 cm x 5 cm</u>
Step-by-step explanation:
<u>Equations we can form</u>
⇒ 2L + 2W = 56
⇒ L + W = 28
- Length is 8 more than 3 times its width
⇒ L = 3W + 8
<u>Substitute in previous equation</u>
⇒ 3W + 8 + W = 28
⇒ 4W = 20
⇒ W = <u>5 cm</u>
<u></u>
⇒ L = 28 - 5 = <u>23 cm</u>
