Answer 1

20Sin(70)= 18.79385

Answer 2

wait... that doesn't seem right

Answer 3

testingtutor, could you double check that?

Answer 4

20 cosec 70°
?

Answer 5

ya, i think that is it

Answer 6

and turing...

Answer 7

The length 'opposite' is 20, what we are looking for is the hypotenuse

Answer 8

I was not trying to break the CoC, I thought I had explained it....

Answer 9

And we know that's a sine.
\[\sin70 = \frac{20}{Hypotenuse}\]

Answer 10

Hence,
\[Hypotenuse = \frac{20}{sin70}\]

Answer 11

\[\tan\theta=\frac ab\implies b=\frac a{\tan\theta}\]
