Answer:
Step-by-step explanation:
is an angle in the third quadrant
To find the reference angle subtract π from it
reference angle = - π =
So we can call the width of the rectangle x.
So then the length would be 4x.
The perimeter would then be 10x.
Since the perimeter is 70, we can say 70 = 10x.
And then simplify that to 7 = x.
So the length of a rectangle would be 28 cm, and the width would be 7.
So to find the area, just multiply length by width.
28*7 = 196 square cm
So the rectangle's area is 196 square cm.

Answer:
50.031 watts
Step-by-step explanation:
Formula
Power = Force * distance / time
The units are critical
distance = meters
time = seconds
force = newtons = kg * m / s^2
Solution
F = m * a
a = 9.81
m = 102 kg
F = 102 * 9.81 = 1000.62 Newtons
T = minute = 60 sec/min * 1 min
T = 60 seconds
d = 3 meters
Power = 1000.62 * 3 / 60
Power = 50.031
