00:00Here I'm in the same sentence, what is sin of 10 inverse 0.75 equal to 10 inverse
00:05At 0.75, that means we have this theta over here, which means 10 theta is equal to 0.75,
00:13What can we write 0.75 as, 3 upon 4, so what can we write as, 3 upon
00:184. Why have we put this now? Because we don't know what a perpendicular base is, how it works.
00:23Suppose, it can be 6 upon 8, it can be 9 upon 12, so we can have 3
00:30Let's give the value of 4, basically, give no value, give 3 upon 4 also, then this question
00:35So what will the hypotenuse go to, underroot, perpendicular square plus base square, this is the hypotenuse in the leaf next to 5
00:43K, now this
00:44Let us ask what does 10 inverse 0.75 mean, 10 theta, at what value of theta is it 0.75
00:53So what we need to find is sin theta of the upright, so 10 theta perpendicular upon base, sin theta
01:00perpendicular upon hypotenuse, perpendicular 3 to hypotenuse 5, k to k cancel, so this comes out to sin theta 3
01:08upon 5, option number 3 is the answer
