If RT = 6 and RS = 9, then RX =<br> A - sqrt(54)<br> B - 13.5<br> C - 7.2<br> D - 4
wolverine [178]

Answer:

Option D RX=4 units

Step-by-step explanation:

we know that

<em>In the right triangle RTS</em>

The cosine of angle TRS is equal to

cos(TRS)=RT/RS

substitute

cos(TRS)=6/9 -----> equation A

<em>In the right triangle RTX</em>

The cosine of angle TRX is equal to

cos(TRX)=RX/RT

substitute

cos(TRX)=RX/6 -----> equation B

∠TRS=∠TRX -----> is the same angle

Match equation A and equation B

6/9=RX/6

RX=6*6/9=4 units

I need help understanding this!
liubo4ka [24]

The basic idea is that multiplying by 10 just moves the decimal point one place to the right.  It makes the number bigger.

4.8 x 10 = 48

4.8 x 10 x 10 = 48 x 10 = 480

Each time you multiply by another 10, the decimal point moves one more time.

The expression 10^5 says you're going to multiply by 10 five times in a row.  So that will move the decimal point 5 places to the right.

So what do you get if you move the decimal in 4.8 five places to the right?
