I just need the work shown for this, the actual answers are next to it but i really need the work done

Answer 1

See below.

Explanation:

For a parallelogram:

(1) Opposite angles are congruent

(2) Opposite sides are congruent

(3) Consecutive angles are supplementary.

(4) Diagonals bisect each other.

14.

Using (3) above,

2x = 110°

x = 55°

Using (1) above,

y = 110°

Using (2) above,

4z - 4 = 3z + 1

z = 5

15.

Using (4) above,

3a - 4 = a + 8

2a = 12

a = 6

2b - 1 = 7

2b = 8

b = 4
