Answer 1

Answer:

given, 5 cot theta = 7.

Therefore, cot theta = 7/5.

Now, dividing the numerator and denominator of ( 7 sin theta + 5 cos theta ) / ( 5 sin theta + 7 cos theta ), i.e., ( 7 sin theta/sin theta + 5 cos theta/sin theta ) / ( 5 sin theta/sin theta + 7 cos theta / sin theta ), we get -----------

( 7 + 5 cot theta ) / ( 5 + 7 cot theta ) [ since, cos theta/ sin theta = cot theta]

= ( 7 + 5 * 7/5 ) / ( 5 + 7 * 7/5 )

= 35/37
