1.

See figure 2.19. Find RP and PSusing the information given in triangle PSR​

Answer»

ANSWER:

\sin(30) = \frac{ps}{rs} \\ ie \: \: \: ps \: = rs \times \sin(30) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 6 \times \frac{1}{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 3 \\ similarly \: \cos(30) = \frac{rs}{pr} \\ thus \: \: \: pr = rs \times \cos(30) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 6 \times \frac{ \sqrt{3} }{2} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3 \sqrt{3}
