The statement above is false.
If the diagonals of a parallelogram form right angles, then the parallelogram is a rhombus (a rhombus is a quadrilateral with four equal side lengths).
Note* = by saying the statement is false is not saying that the scenario presented in the statement cannot occur. If the rectangle was a square, then its diagonals can form right angles since a square is also a rhombus. However, if a rectangle was NOT a square, its diagonals would not form right angles. A true statement is a statement where ALL cases fit the said requirement(s).
The statement can also be corrected by saying:
If the diagonals of a parallelogram are congruent, then the parallelogram is a rectangle.
All rectangles (even a square) have congruent diagonals, so this statement would be true.
Hope this helps!
We know that ON = 80 cm and ∠ O = 37°.
cos 37° = 4/5
Adjacent / Hypotenuse = cos∠O
80/OP = cos 37°
80/ OP = 4/5
OP = 80 : 4/5 = 80 · 5/4 = 100
Answer:
d. 100 cm.
A 7.2-7.3-7.4-7.5-7.6
b 5.60-5.61-5.62-5.63-5.64
Answer:
79.12 miles.
Step-by-step explanation:
That would be 8.6 * 9.2 = 79.12 miles.
