Dan's father is an orange farmer and he brought 32 orange it to class today if each child got four oranges and five children did not want oranges how many children are in the class?

 There are 13 children.

Step-by-step explanation:

1. Let's call x the number of children in the classroom. We know that each child received 4 oranges, except 5 of them.

2. There were 32 oranges in total.

3. We can write this problem as an equation that represents the number of oranges distributed, as follows:

4. Now we solve the equation to find the value of x:

5. There are 13 children in the classroom. 8 of them received oranges and the rest did not.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
