Question

sec(90+A) +xsinA tan(90+A)= cos(90+x) find the value of x​

Answer 1

Answer:

sec( 90+A) + x sin A tan (90+A) cos (90+A) -cosec A+y sin A (cot a) = sin Ax sin A (cos / A sin A) =-sin A cosec Ax (-cos A) = (1/ sin A ) -sin Ax (-cos A )= (1-sin square)/sin A x=(sin - square A -1)/sin A cos A
