Answer:

sin teta = 5/3 it can be also said as                                                                                                        sin teta = opposite side/hypotenuse                                                                                                                      so if  opposite side is 3                                                                                            hypotenuse is 5

when we appply pythagoras formula we get adjacent said as 4

so cos teta = adjacent / hypotenuse        = 4/5

by the formula (1 - (4/5)2)

1/1 - 16/25 taking lcm

25-16/25

ans wer is 9/25
