Question

In RST, mR = 90, mS = 60, and mT = 30. Which of the following statements about RST are true?

Answer 1

A. ST = 2 RS
B. RT = 2 RS
C. RT = ST
D. RS = ST
E. ST = RS
F. RT = RS

Answer 2

this is a 30-60-90 triangle R is the right angle so ST is the hypotenuse. RS is the shortleg and RT is the longer leg of the triangle. In a 30-60-90 triangle Hypotenuse = 2 * Shorter leg. So ans. is ST = 2 RS Choice A
