Answer:
See the attached figure which represents the problem.
As shown, AA₁ and BB₁ are the altitudes in acute △ABC.
△AA₁C is a right triangle at A₁
So, Cos x = adjacent/hypotenuse = A₁C/AC ⇒(1)
△BB₁C is a right triangle at B₁
So, Cos x = adjacent/hypotenuse = B₁C/BC ⇒(2)
From (1) and (2)
∴ A₁C/AC = B₁C/BC
using scissors method
∴ A₁C · BC = B₁C · AC
Answer:

Answer:
Simple
Rise/Run
for one week they run 10 miles
2 weeks 20 miles
3 weeks 30 miles
4 weeks 40 miles
the rate of change would be 10/1 (Why? Because you rise +10 each time per week.)
divide that it would be 10 (:
