1)An isosceles triangle with equal sides of 5 inches and a base of 6 inches is inscribed in a circle. What is the radius, in inches, of the circle? Express your answer as a mixed number.
2)A quadrilateral has angles of q,4q+12 degrees , 3q+21 degrees, and 7q-48 degrees. Find the largest angle of the quadrilateral, in degrees.
3)The area of a trapezoid is 80 . The length of one base is 4 units greater than the other base, and the height of the trapezoid is 12. Find the length of the median of the trapezoid.
(I got 20 which is incorrect, I miss read and i think i found the preimeter instead of the length of the median)
4)Let WXYZ be a trapezoid with bases $\overline{XY}$ and $\overline{wz}$. In this trapezoid$\angle ZXW = 81^\circ$, $\angle XWZ = 62^\circ$, and $\angle XYZ = 137^\circ$. Find $\angle YXZ$, in degrees.
(I got 32 which is wrong)
5)In trapezoid EFGH, $\overline{EF} \parallel \overline{GH},$ and P is the point on $\overline{EH}$ such that EP:PH=1:2 . If the area of triangle PEF is 8, and the area of triangle PGH is 21, then find the area of trapezoid EFGH.
(it's not 58 or 72)
6)In trapezoid ABCD, $\overline{AB} \parallel \overline{CD}$ . Find the area of the trapezoid.
7)In trapezoid PQRS,$\overline{PQ} \parallel \overline{RS}$ . Let X be the intersection of diagonals $\overline{PR}$ and $\overline{QS}$. The area of triangle PQX is 27 and the area of triangle RSX is 75 Find the area of trapezoid PQRS.
8)In parallelogram EFGH let M be the point on $\overline{EF}$ such that FM:ME=1:2, and let N be the point on $\overline{EH}$ such that HN:NE=1:3. Line segments $\overline{FH}$ and $\overline{GM}$ intersect at P and line segments $\overline{FH}$ and $\overline{GN}$ intersect at Q. Find PQ/FH.
