See the figure attached to better understand the problem

we now that

in the triangle ABC
tan alfa=126/120----------> 1.05
alfa=arctan (1.05)-------> alfa=46.40°

in the triangle ADC

sin alfa=DC/120----------> DC=sin(46.40°)*120---------> DC=86.90 units

What is 24 percent of 94
Sphinxa [80]

Answer:

22.56

Step-by-step explanation:

1. We assume, that the number 94 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 94 is 100%, so we can write it down as 94=100%.

4. We know, that x is 24% of the output value, so we can write it down as x=24%.

5. Now we have two simple equations:

1) 94=100%

2) x=24%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

94/x=100%/24%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 24% of 94

94/x=100/24

(94/x)*x=(100/24)*x       - we multiply both sides of the equation by x

94=4.1666666666667*x       - we divide both sides of the equation by (4.1666666666667) to get x

94/4.1666666666667=x

22.56=x

x=22.56
