So in this question, we can let the hypotenuse of the triangle is h.
00:08
So it is a right triangle with hypotenuse h.
00:12
So the other three sides of the triangle are h is hypodinoos.
00:19
Other two sides, h, sine theta, then h cos theta.
00:27
So these are the three sides of this right triangle.
00:31
And in question it is said that these three are in gp.
00:36
So these three are in gp.
00:40
Okay.
00:41
In a gp, we can, we know that product of first and third term is equal to the square of second term.
00:51
That is, if three terms, that is a, a, r and a, r square in a gp, then product of first and third term, that is a into a r square is equal to the square of second term that is a r square sorry a r old square so this is the property of a gp so sorry sorry okay so we can apply this this into our gp so so h sine square, sorry, h square sine square, it is a square of middle term, that is h square sine square theta...
