2/3 times x = 4/9 <br> Solve for X<br> 10 points

BabaBlast [244]

Answer:

The answer is 2/3

Step-by-step explanation:

Let's solve your equation step-by-step.

2/ 3(x)=4/9

Step 1: Multiply both sides by 3/2.

( 3/2)*(2/3*x)=(3/2)*(4/9)

so this means the answer is 2/3

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.
