HOT! Listen to Jason Ling's Music now!
In the figure, ABC is a straight line. CD = 7 cm, BC = 4 cm and sin angle DBC = 4/5 and cos angle DBA = 3/5. FInd, giving your answer as fraction in the lowest terms, the value of sin angle BDC. Ans : 16/35
thanks to all.

This is only 1 part of the question right?
Use sine rule
sin DBC / 7 = sin BDC / 4
so sin BDC = 4/7 * 4/5 = 16/35
