P+Q+R=180 then to prove (cosp/sinq. sinr) + (cosq/sinr. sinp) + (cosr/sinp. sinq)=2

Follows are the solution to this question:

Step-by-step explanation:

Given:

prove that

Solving the L.H.S part:

Solve the above value by taking L.C.M:

multiply the above value by :

So, L.H.S=R.H.S

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
