vova2212 [387]

Answer:

2 < or equal to (t) < or equal to 1000

Step-by-step explanation:

2 is the profit of the (t) amount of t shirts so the amount should be greater than or equal too 1000 because if they have 500 shirts 500 x 2 is 1000

Please Help It Is Past Due!
Step2247 [10]

Explanation:

First we consider ΔABC and ΔBCD,

∠C=∠C  (common)

∠B=∠D=90\textdegree

So, ΔABC ≈ ΔBCD (By AA similarity rule )

So by taking corresponding sides in ratios we get

\frac{AB}{BD}=\frac{AC}{BC}=\frac{BC}{CD}      

Now

AC.CD=BC.BC\\BC^{2} =AC.CD              -------- Eqn (1)

Similarly,

We consider ΔABD and ΔABC

∠A=∠A (Commom)

∠B=∠D=90\textdegree

So,

ΔABD ≈ ΔABC (By AA similarity rule )

So by taking corresponding sides in ratios we get

\frac{BC}{BD}=\frac{AC}{AB}=\frac{AB}{AD}  

Now,

AB.AB=AC.AD\\AB^{2} =AC.AD              --------Eqn (2)

By Adding both the equation we get

AB^2+BC^2=AC.CD+AC.AD\\AB^2+BC^2=AC(CD+AD)\\AB^2+BC^2=AC.AC\\AB^2+BC^2=AC^2

Hence, we proved the pythagorean theorem by using similarity of triangle.
