Answer:
The perimeter of a parallelogram = 58 ft
Step-by-step explanation:
A parallelogram is a quadrilateral with opposite sides parallel and equal in length. Opposite angles are also equal.
Area of parallelogram = base × height
Area = 162 ft²
area = bh
b = ?
h = 9 ft
162 = 9b
divide both sides by 9
b = 162/9
b = 18 ft
The perimeter of a parallelogram = 2(b + s)
where
b = base
s = the other sides
The perimeter of the parallelogram = 2(b + s)
The perimeter of the parallelogram = 2(18 + 11)
The perimeter of the parallelogram = 2(29)
The perimeter of the parallelogram = 58 ft
Answer:
See below
Step-by-step explanation:
The three angles inside of the triangle sum to 180
11x + 4 + 3x + 78 = 180
14x +82 =180
x = 7
then B = 11x + 4 = 11(7) + 4 = 81 degrees
C = 3x = 21 degrees
