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
Answer:
the angle of x measures 16.6
Answer:
66
Step-by-step explanation:
One way of solving this is to first add 12 to get the number to 0. Then add another 54 to get to 54 degrees. Then you can add these two numbers together to get 66.
Answer:

Step-by-step explanation:
Answer:
A = 173 m²
Step-by-step explanation:
P = 60m = 3L => L = 60 : 3 = 20 m
A = L×h/2 = 20m×17.3m/2 = 10m×17.3m = 173 m²
