150010+ 17509\frac{15 \cot \theta+17 \sin \theta}{8 \tan \theta+16 \sec \theta}uate शक

Answer»

cos theta = √ ( 1 - sin^2 theta) =

√ ( 1 - (15/17)^2 )

√ (289 - 225) / 17 =

√64 / 17 =

8/17

cottheta=cos/sin=8/15tan=sin/cos=15/8sec=1/cos=17/8hence in given equation15*8/15+17*15/17/8*15/8+16*17/8=8+15/15+17/2=23/30+17/246/30+17=46/47
