Your keys drop from the top of the tower and fall straight to the ground. you want to know how far from the base of the keys landed. draw a right triangle that will you solve the problem. label each triangle with the information you know

Δ ABC is the required triangle.

Step-by-step explanation:

Since the person is standing at the top of tower.

let the height of tower be 'h' and 'b' be the distance from base of tower to the point where keys are dropped.

Consider, ABC be the right angled triangle with AB be the tower and A be the point where person is standing and C denotes the point where keys dropped finally.

Alpha (α) be the angle at which keys is dropped.

BC denotes the distance from foot of tower to the keys.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
