Answer:

Explanation:

Sum of interior angles in a triangle is 180degree.

<B + 15degree + 45degree = 180degree

<B = 180 - 45 - 15 = 120 degree

By sine rule,

sin<B / AC = sin<C / AB = sin <A / BC

sin120degree / 200 = sin15degree / AB = sin45degree / BC

AB = 200*sin15degree/sin120degree

= 59.77

BC = 200*sin45degree/sin120degree

= 163.30
