<PRE><B>Question 288320</B>
Angle RTS is a right angle; segment RT=8, RS=17, VT=12, and VS=9. What is the measure of angle V? Explain.
-----------------
If you do not have the picture, draw it.
----
Use Pythagoras to find TS = x
----
17^2 = 8^2 + x^2
x^2 = 225
x = 15
------------------------
Use the Law of Cosines to find measure of angle V
cos(V) = (12^2+9^2-15^2)/(2*12*9)
cos(V) = 0/216 = 0
V = 90 degrees
