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°.

The degree measurement of angle A is already equal to 50 degrees.

Add the two expressions.<br><br> 2x + 6 and 6x −1<br><br> Enter your answer in the box.
MA_775_DIABLO [31]

Answer:

8x +5

Step-by-step explanation:

The sum is found by combining "like" terms—those that have the same arrangement of variables.

The first expression, 2x +6, has terms 2x and 6.

The second expression, 6x -1, has terms 6x and -1.

In each case, the first term listed is first-degree in the variable x. These are "like" terms, so can be added:

... 2x +6x = (2+6)x = 8x

The second term listed in each case is a constant. These are "like" terms, so can be added:

... 6 + (-1) = 5

Then the sum of the given expressions is the sum of the results from adding like terms:

... 8x + 5
