Step-by-step explanation: We are given to find the size of SR in the right-angled triangle SRQ as displayed in the figure.
You are watching: What is the length of ? 9 units 12 units 15 units 18 units
Since RT is perpendicular to the hypotenuse SQ, therefore triangle RTQ and SRT are additionally right-angled triangles at edge RTQ and RTS respectively.
Also, RQ = 20 units and TQ = 16 units.
Using Pythagoras organize in triangle RTQ, us have
Now, due to the fact that RT is perpendicular to the hypotenuse that ΔRST, so us get
Again, utilizing Pythagoras theorem in right-angled triangle RST, we get
Thus, the size of SR is 15 units.
Option (C) is CORRECT.

You and also a friend space playing a game using a spinner separated into 4 equal sections, numbered 1 v Which the the following wou
You win if you spin any number except 3, otherwise her friend wins
Because the spinner is split into equal sections, there is an same probability of spinning any type of number. In this case, you victory by spinning a 1, 2, or 4, and your friend only wins by rotate a 3. The probability of friend winning is 34, when the probability of your friend win is only 14.
