Hi,

Sorry this is late.

Remember: soh cah toa

sin A: 3/5

cos A: 4/5

Your answer would be A.

Have a great day!

$\tt 4 \frac{1}{2} - 1 \frac{1}{3}$

$= \tt \frac{9}{2} - \frac{4}{3}$

$= \tt \frac{27 - 8}{6}$

$\tt = \frac{19}{6}$

${\orange{\boxed{\red{ \tt = 3 \frac{1}{6} }}}}$

Which expressions represent rational numbers? check all that apply. startroot 6 endroot startroot 9 endroot startroot 64 endroot

dimaraw [331]

Answer:

Which statements about square roots are true? Check all that apply.

The square root of a positive number cannot be negative.

All positive numbers have two square roots.

StartRoot 18 EndRoot= 9 because 9(2) = 18.

StartRoot 49 EndRoot= 7 because 7(7) = 49.

StartRoot 25 EndRoot = 5 because 52= 25.

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.
