Question

1A) Quad ABCD is inscribed in the circle. Find x. *

1B) Using your answer from above, what is angle A? *

Answer 1

Explanation:

2x + 9° + 3x + 1° =180° (opposite angles of a cyclic quadrilateral are supplementary)

5x + 10° = 180°

5x = 180° - 10°

5x = 170°

x = 34°

Now

Angle A

= 2 * 34° + 9°

= 77°
