The resultant of two forces acting at a point at right angles to each other is 40 pounds. If the horizontal force is 30 pounds what is the other force?​

10√7 pound

Step-by-step explanation:

R = √A² + B² + 2ABcos∅

=> 40 = √30² + B² + 2ABcos0°

=> 40² = 30² + B² + 0

=> 1600 - 900 = B²

=> √700 = B

=> 10√7 = B

Note that if R = 50*, B = 40 pounds

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
