Answer:
EHD = 90
ow this one is easy u dont really need to do any counting, since The arc has the same measure as the angle because its from the center arc.
but if you were to count them they would look like this:
180 = EHD +90 to get rid of the 90 so we can bring it to the other side we'll have to subtract both sides by 90
180-90= EHD +90-90
90 = EHD
