Question

Given
15 cat A = 8, find sind
sin A seci​

Answer 1

Answer:

please note question in proper way.

15 cot = 8

cot =8/15

then, using Pythagoras theorem

${ab}^{2} = {ac}^{2} + {bc}^{2} \\ = 15 {}^{2} + 8 { }^{2} \\ = 225 + 64 \\ = 289 \\ ab = { \sqrt{289} }^{} \\ ab = 17$

sin A=BC/AB=15/17
