Question

find sin B give the answers. please! fast Thanku.​

Answer 1

Answer:

please Mark as brilliant answer

Answer 2

Answer:

By Pythagoras Theorem,

${(ab)}^{2} = {(bd)}^{2} + {(ad)}^{2} \\ {13}^{2} = {5}^{2} + {ad}^{2} \\ 169 = 25 + {ad}^{2} \\ 144 = {ad}^{2} \\ 12cm = ad$

Thus,

$sin(b) = \frac{opp.}{hyp.} \\ = \frac{ad}{ab} \\ = \frac{12}{13}$

Hope this helps.

Thanks.
