Question

hey freinds, plz give the answer of 14 question. hope for best to best answers. i will mark if i like anyone answer

Answer 1

<BAC = 60-15 = 45°

<BCA = 180 - 90 - 60 = 30° from triangle APC

by using sine rule

$( \frac{ab}{sin \: 30} ) = ( \frac{bc}{sin \: 45} )$
we know that AB = 35 m

BC = sin 45° *(35/sin 30)
BC = 35√2 m

Any doubts comment below :))
