Let X and Y be random variables representing the side lengths of the rectangle. Then the area of the rectangle is given by the random variable XY.
We have
or approximately 0.1534.
Answer:
40
Step-by-step explanation:
It’s same as <5
70 feet
3.5 times 20=70.
: c2 = a2 + b2 - 2ab cos C
c²=20²+15²-2×15×20×cos50
c²=400+225-600×0.64
c²=241
c=√241=15.5ft
