Mathematics

Explanation:

Angles of rotational symmetry are the angles by which you can turn a figure about its center of symmetry so that the rotated figure is indistinguishable from the original.

<u>Example</u>

A square has angles of rotational symmetry of 90°, 180°, and 270°. Rotating a square around its center by any of these angles gives you back exactly the same square.

__

The number of angles of rotational symmetry (including 0°) is the <em>degree</em> of rotational symmetry. A square has rotational symmetry of degree 4.

I will mark you brainliest for the right answer and you must HURRY to get it! 15 points!
DENIUS [597]

A triangles three angles always sum up to 180 degrees. We must find angle B.

We already have angle A and C, so it's quite simple.

Angle A is 28*, and angle C is 36*

We add these two together

28 + 36 = 64

Now we subtract

180 - 64 = 116

Angle B = 116*


Hope this helps you! (:
