The given parallelogram is a rhombus
Solution:
Option A: Rhombus
Let us recall the property of rhombus.
- Diagonals bisect each other at right angles.
- Opposite angles are congruent.
Here diagonals bisect the angles equally each 72°.
Opposite angles are congruent(72° + 72° = 144°).
Hence the given parallelogram is a rhombus.
Option B: Rectangle
Let us recall the property of rectangle.
- Diagonals bisect each other.
- All the angles of a rectangle are 90°.
Here 72° + 72° = 144°, not 90°.
So, the given parallelogram is not a rectangle.
Option C: Square
Let us recall the property of square.
- Diagonals bisect each other.
- All the angles of a square are 90°.
Here 72° + 72° = 144°, not 90°.
So, the given parallelogram is not a square.
Answer:
The desired ordered pair is (1/2, 3/2).
Step-by-step explanation:
Let's use the substitution method here to determine either x or y first:
x = 5y - 7 (given). Then 5y - 7 can be substituted for x in x + 5y = 8:
5y - 7 + 5y = 8.
Combining like terms, we get 10y = 15, so that y = 3/2.
Find x by substituting 3/2 for y in x = 5y - 7: x = 5(3/2) - 7 = 15/2 - 14/2 = 1/2
The desired ordered pair is (1/2, 3/2).
