Can anyone help me please

Part a) HI = 8 because the little arc on each angle indicated they are all equal lengths. So if GH is 8, HI is also 8.
part b) measure of angle K is 110 degrees because if we know that LK and KJ are both 11 on the side, the angles should be equal, so angle L should also be 35 degrees. Once we know two angles, just subtract them from 180 to find the third angle.
180-35-35 = 110
