In triangle QRS QT=5 and TS=22 what is RT? Explain!!

Anton [14]

Answer:

$\large\boxed{RT=\sqrt{110}\approx10.49}$

Step-by-step explanation:

ΔTQR and ΔTRS are similar (AA). Therefore the sides are in proportion:

$\dfrac{RT}{QT}=\dfrac{TS}{RT}$

We have QT = 5m ans TS = 22m. Substitute:

$\dfrac{RT}{5}=\dfrac{22}{RT}$ <em>cross multiply</em>

$RT^2=(5)(22)$

$RT^2=110\to RT=\sqrt{110}$

I AM IN DESPERATE NED OF QUICK HELP PLEASEEEEEEEEEEEEEEEEEEEEEE!!!!!!!!!!!!!!!!!!!!!!

rosijanka [135]

Answer:

Step-by-step explanation:

To solve this equation, we need the formula for perfect squares:

$(a + b)^2 = a^2 + 2ab + b^2$

$(a - b)^2 = a^2 - 2ab + b^2$ <em>this is the formula we will use because the signs match the one in the question</em>.

Knowing these, we can set up an equation that assumes that the answer we will end up with is a perfect square.

Work:

$(v - x)^2 = v^2 -8v + x^2$

this is the setup for being able to solve for the unknown $x$ , now we need to solve for $x$ .

$(v - x)^2 = v^2 - 8v + x^2$ (I replaced $2ab$ with $8v$ because I'm setting up this question to be a perfect square).

$(v - x) (v - x) = v^2 - 8v + x^2$

multiply the left side. Remember that your answer will not be $v^2 + x^2$ , but $v^2 - 2vx +x^2$ .

$v^2 - 2vx + x^2 = v^2 + 8v + x^2$

Divide like terms and isolate the variable. In this case, $v^2$ and $x^2$ are on both sides, so dive them and they will be canceled out.

$2vx = 8v$

divide by $2v$ and you will have your value for $x$ .

$x = 4$

Now we plug $x$ into our original equation equation for perfect squares.

$(v - 4)^2 = v^2 - 8v + 16$

Our final answer is 16.
