22 + (30 - 4) divided by 2
30 - 4 = 26
26/2 = 13
22 + 13 = 35
35
18 + (22 - 4) divided by 6
22 - 4 = 18
18 divided by 6 = 3
18 + 3 = 21
21
Answer:
BD = 28
CD = 22
A = 124
C = 56
D = 124
Step-by-step explanation:
The above quadrilateral is a parallelogram
(1) Opposite angles are equal.
(2) Opposite sides are equal and parallel.
(3) Diagonals bisect each other.
(4) Sum of any two adjacent angles is 180°
so
BD = AC = 28
CD = AB = 22
A = 180 - B = 180 - 56 = 124
C = B = 56
D = A = 124
Q-1.8+1.8=14+1.8= Q=15.8 hope this helps
