if a,b are different values of x(angle) satisfying the equation 5cosx+12sinx=11 the value of sin(a+b)=. options : 1)119/120 2)5/12 3)120/169 4)12/5

Question

Vikas TU · Answer

5cosx+12sinx=11 12sinx = 11 – 5cosx squaring both sides, 144sin^2x = 121 +25cos^x – 110coss write sin^2x = 1 – cos^2x then assume sin x = t, and then form the qudratic and solve them. and add them and ake their sin.
