Question

Sin37 is 3/5 and sin 74 is

Answer 1

Answer: 24/25

Explanation:

$sin(2\alpha )=2sin(\alpha )cos(\alpha)$ Let alpha be 37 degree

so,$sin(37^0)=\frac{3}{5}$

now, by using a right triangle we can get the value of $cos(37^0)=\frac{4}{5}$

Putting values in formula

$sin(74^0)=2*\frac{3}{5}*\frac{4}{5} = \frac{24}{25}$
