PLEASE ANSWER THESE 5 QUESTIONS WITH FULL STEPS.

Answer 1

Step-by-step explanation:

1) sum of two angles equal to 200 degrees

Let other two equal angles equal to x

sum of all four angles =360 Degrees

X+X+200=400

2x+200=400

2x=400-200

X=200/2

X=100 degrees

2) diagonals bisect each other in a parallelogram

X+3=18

X=18-3

=15

X=15

X+y=20

15+y=20

y=20-15

y=5

3)
