What is the length of SR ? 9 units 12 units 15 units 18 units

astraxan [27]

Answer: THe correct option is (C) 15.

Step-by-step explanation: We are given to find the length of SR in the right-angled triangle SRQ as shown in the figure.

Since RT is perpendicular to the hypotenuse SQ, so triangle RTQ and SRT are also right-angled triangles at angle RTQ and RTS respectively.

Also, RQ = 20 units and TQ = 16 units.

Using Pythagoras theorem in triangle RTQ, we have

$RQ^2=RT^2+TQ^2\\\\\Rightarrow RT=\sqrt{RQ^2-TQ^2}\\\\\Rightarrow RT=\sqrt{20^2-16^2}\\\\\Rightarrow RT=\sqrt{144}\\\\\Rightarrow RT=12.$

Now, since RT is perpendicular to the hypotenuse of ΔRST, so we get

$ST\times TQ=RT^2\\\\\Rightarrow RS\times 16=144\\\\\Rightarrow RS=\dfrac{144}{16}\\\\\Rightarrow RS=9.$

Again, using Pythagoras theorem in right-angled triangle RST, we get

$SR^2=RT^2+ST^2\\\\\Rightarrow SR=\sqrt{144+81}\\\\\Rightarrow SR=\sqrt{225}\\\\\Rightarrow SR=15.$

Thus, the length of SR is 15 units.

Option (C) is CORRECT.

Jake went on a riverboat tour. After returning from the tour, he was curious to know the speed at which the boat was going. Duri

atroni [7]

I'm sorry I'm too lazy to read all of that. However, I did get the main point. The river was going at 3 mph. Since he wanted to travel 10 miles upstream and downstream, you would have to subtract 20 by 3. This would mean he was going at a speed of 17 mph.
