Juan sees a maple tree and a pine tree in the forest. He knows that the pine tree is 20.04 feet tall. On a sunny day, the shadow of the pine is 5.4 feet long while the maple’s shadow is 10 feet long. Estimate the height of the maple tree. A. about 60 feet

B. about 23 feet

C. about 57 feet

D. about 37 feet

the correct answer is x/3+10≥32

hope this !

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

1st part is 64,000,000

2nd part 500,000

i think its a.
