Please help me im in 7th grade its for check in!

Find the solutions for a triangle with a =16, c =12, and b = 63º

Factor the polynomial expression x6 – x3 – 20

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
