Question

how to solve this please explain step by step, I have only 1 point I can't ask it again and again
"1/√2/sin r=1.414"​
and yes the answer is 30​

Answer 1

$\frac{ \frac{1}{ \sqrt{2} } }{ \sin(r) } = 1.414 \\ \\ \frac{1}{ \sqrt{2} \sin(r) } = \sqrt{2} \\ \\ \frac{1}{ \sin(r) } = \sqrt{2} \times \sqrt{2} \\ \\ \sin(r) = \frac{1}{2} \\ \\ \sin(r) = \sin(30) \\ \\ therefore \: r = 30 \: \: \: \: \: \boxed{ \red{ \: ans.....}}$
