Answer:
No, but all parallelograms are quadrilaterals.
Step-by-step explanation:
Take a trapezoid, for example. A trapezoid is a quadrilateral because it has 4 sides, but it does not contain 2 sets of parallel sides thus making it not a parallelogram.
It is unlikely but possible to generate the same number 3 times because each number has the same probability of being generated at random.

Answer:a
Step-by-step explanation:
Answer:
AB ≈ 7.08
Step-by-step explanation:
Cos θ = adjacent / hypotenuse
where θ = 20° , adjacent = 7 and hypotenuse = AB
cos 20 = 7 / AB
cos 20 × AB = 7
AB = 7/Cos 20
AB = 7 / 0.989
AB = 7.077
AB ≈ 7.08
