A pair of congruent angles are described as follows: The degree measure of one angle is three more than twice a number, and the
Fiesta28 [93]

Answer:

The measure of the angles in degree is 57.5 degrees

Step-by-step explanation:

If two angles are congruent, they are equal in value

Let the number be x

2x + 3 = 3x-54.5

Thus;

3x-2x = 54.5 + 3

x = 57.5

Point F' corresponds to point D. point E'. point F. point E.
Zepler [3.9K]

Answer:

  F' corresponds to point F

Step-by-step explanation:

When a point is the result of some transformation, we often designate that result using the base name of the original, with a prime (') added. In this case, we expect that F' is the transformation of point F.

__

<em>Comment on point naming</em>

Of course, points can be given any name you like. These conventions are adopted to aid in communication about transformations and correspondence between points. It would be unusual--even confusing, but not unreasonable, for point F' to correspond to point D, for example. In the case of certain transformations, point F' may actually <em>be</em> point D.

Need some help please would really be greatful
Gnesinka [82]

Answer:

x = 100°

Step-by-step explanation:

Actually the drawing is very inaccurate, so it is a regular pentagon, otherwise x would be 60° and none of the answers would fit.

The formula for finding the sum of all angles in a polygon is:

(n-2) * 180°

n is the number of sides

Here n = 5, so the sum of all angles is (5-2) * 180° = 540°

x + 2x + 86 + 92 + 62 = 540

3x = 300

x = 100
