<h3>
Answer: False</h3>
Explanation:
If a parallelogram has a line of symmetry through each pair of opposite sides, then we have a rectangle.
But if a parallelogram has a line of symmetry through each pair of opposite vertices, then we have a rhombus.
A square is a combination of both cases above.
The statement "A parallelogram which has a line of symmetry is a rectangle" is sometimes true. Overall its false because it implies that all parallelograms with this property are automatically a rectangle.
Answer:
3^2 + x^2 = 9^2
9 + x^2 = 81
x^2 = 72
x =
, which is about 8.5
Cosine X = 3/9
Cosine X = 1/3
angle x= 70.5
If angle x= 70.5, angle z = 19.5 degrees.

Find Base Area :
------------------------------------------
Volume = Base Area x Height
540 = Base Area x 15
Base Area = 540 ÷ 15
Base Area = 36m²
------------------------------------------
Find Length :
------------------------------------------
The base is a square
Area = Length²
36 = Length²
Length = √36
Length = 6m
------------------------------------------
Find Perimeter :
------------------------------------------
Perimeter = 4 x Length
Perimeter = 4 x 6 = 24 m
------------------------------------------
Answer: Perimeter = 24m
------------------------------------------
Answer:
Area = 294 cm^2
Volume = 343 cm^3
Step-by-step explanation:
Simply plug in s = 7 into the given equations.
