How do you solve this for h?

-multiply both sides by 2, so you will have 2A= h(b+c)

- divide both sides by (b+c), so you will have 2A/(b+c)=h and this is your final answer

See below.

Step-by-step explanation:

Jay is correct.

If you draw a semicircle with a diameter and use the center of the circle as the point of rotation, the figure will only look the same as the original when it is rotated 360 degrees. This gives the semicircle an order of rotation of 1. That means that once you start rotating a semicircle, it only looks like itself after a full 360-degree rotation. It does not have rotational symmetry.
