How many football fields (with dimensions 300 feet by 160 feet) are needed to accommodate 50,000 students if each student has 4 square feet to stand?

a² + b²= c²

24² + 7² = c²

c= 25

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,

the answer

b. they are parallel and will never intersect.
