HELPPP!!! QUICK

Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the quadrilateral. You must use the fact that opposite angles in a quadrilateral are supplementary.

Show me:
(a) supplementary equation used to solve for x (1 point)
(b) all math used to calculate for x (1 point)
(c) correct value for x (1 point)
(d) plugging x into expressions for angles A, C, D (1 point)
(e) show all math used to calculate the measures of angles A, C, D (2 points)
(f) all math used to calculate the measure of angle B (1 point)

Answer:

Explanation:

Supplementary means the angles add up to 180°.

Add the given angles and set equal to 180°

To solve, combine like terms, add 10, divide by two to get x all by itself.

Replace x with 95 to find the measures of Angles A, C, D.

Use the supplementary definition a second time to find the measure of Angle B.
