Question

with explaining ok naa ​

Answer 1

Answer:

Explanation:

α = 37°

β = 37°

so ,

sin 74°  =  0.96°

Answer 2

Answer:

Given:

$sin \alpha = \frac{3}{5} \\ cos \beta = \frac{4}{5}$

Now,

By using Pythagoras theorem,

we get,

$cos \alpha = \frac{4}{5} \\ sin \beta = \frac{3}{5}$

As we know that,

$\sin( \alpha+\beta ) = \sin( \alpha ). \cos( \beta) + \cos( \alpha) . \sin( \beta)$

$\sin( \alpha + \beta) = \frac{9}{25} + \frac{16}{25} = \frac{25}{25} = 1$

$\alpha + \beta = \frac{\pi}{2}$
