Which of the following is an adjacent pair of angles

If eh = hg and hg=16, find the diameter of k

Which expression gives the exact value of x?

Does the construction demonstrate how to copy an angle correctly using technology a) yes the distance between points a and f was used to create circle h b) yes the distance between points f and g was used to create circle h c) no the distance between points a and f was used to create circle h d) no the distance between points f and g was used to create circle h
