Which of these figures has rotational symmetry
Umnica [9.8K]

9514 1404 393

Answer:

  A

Step-by-step explanation:

The parallelogram has rotational symmetry of degree 2. It looks the same after rotation by 180°.

_____

<em>Additional comment</em>

When a figure only looks like itself after a full rotation of 360°, it is said to have rotational symmetry of degree 1. All of the figures here will return to their original appearance after one 360° rotation. So, we assume the intent of the question is to identify figures with a <em>rotational symmetry of degree greater than 1</em>.

stellarik [79]

Figure out 5% of 30,000: .05 x 30,000 = 1,500

Multiply 1,500 by the number years, but subtract the first year (as you don't receive a bonus) : 1,500 x 39 =  58,500

Now add the bonus with the initial salary: 58,500 + 30,000 = 88,500.

THE ANSWER IS $88,500!!! :)
