Answer:

The degree measurement of angle A' is 130°.

Step-by-step explanation:

Given information: ∠A = 130° and ∠B = 50°.

Sam rotated parallelogram ABCD 90° clockwise around the origin. If angle A is 130° and angle B is 50°.

Rotation is a rigid transformation, it means the size and shape of a figure remains same after rotation. In other words we can say that preimage and image are congruent.

ABCD\cong A'B'C'D'

Corresponding parts of congruent figures are congruent.

\angle A\cong \angle A'

m\angle A=m\angle A'

130^{\circ}=m\angle A'

Therefore the degree measurement of angle A' is 130°.

A rectangle has an area of 99 square in. What is the length of the long side?
OLga [1]

Answer:

The longer length is either 99, 33 or 11 inches

Step-by-step explanation:

Given

Area = 99

Required

The length of the longer side

Area of a rectangle is:

Area = Length * Width

List out all possible products that give 99 [Assume the dimension are whole numbers]

Length * Width = 99 * 1 = 99

Length * Width = 33 * 3 = 99

Length * Width = 11 * 9 = 99

List out the longer factors

L = \{99, 33, 11\}

<em>Hence, the longer length is either 99, 33 or 11 inches</em>
