Question

Can yall plz tell me the answer its urgent!​

Answer 1

Answer:

Solution ⬇️

✍️Given=LLmn=90⁰,angle L=50⁰,angle N=40⁰

✍️To find:Cos50⁰=??

$= = > sin50 {}^{0} = \frac{opposite \: side \: of \: angle \: l}{hypotenuse} = \frac{mn}{ln}$

$= = > \cos50 {}^{0} = \frac{adjacent \: side \: of \: angle \: l}{hypotenuse} = \frac{lm}{ln}$

$= = > tan40 {}^{0} = \frac{opposite \: sides \: of \: angle \: n}{adjacent \: side \: of \: angle \: n} = \frac{lm}{mn}$

$= = > cos40 {}^{0} = \frac{adjacent \: side \: of \: angle \: n}{hypotenuse} = \frac{lm}{ln}$
