Answer:
It could be
Step-by-step explanation:
The calculation of sides of a rectangular triangle can be done by applying the Pythagorean theorem (the sum of the squares of the legs is equal to the square of the hypotenuse), both legs must form a right angle, and the value of the hypotenuse must be different from the legs. In the example what you give could be a value of one leg and the other of the hypotenuse.
Forces in direction x:
fx1 = 100 * cos (50) = 64.28
fx2 = 50 * cos (160) = - 46.99
The resultant is:
fx = fx1 + fx2 = 17.29
Forces in direction y:
fy1 = 100 * sine (50) = 76.60
fy2 = 50 * sine (160) = 17.10
The resultant is:
fy = fy1 + fy2 = 93.70
The magnitude of the resulting force is:
f = root (fx ^ 2 + fy ^ 2)
f = root ((17.29) ^ 2 + (93.70) ^ 2)
f = 95.28
The angle is:
theta = atan (fy / fx)
theta = atan (93.70 / 17.29)
theta = 79.55 degrees
Answer:
The direction and magnitude of the resultant force are:
f = 95.28 pounds at theta = 79.55 degrees
Answer:

Answer:D
Step-by-step explanation:
You would distribute the 3/4 into both terms and by multiplying you get that answer
To get to 20 minutes from 2 minutes you multiply by 10, do the same to the 30 problems to get 300. The answer is 300 problems in 20 minutes.
