Perimeter is the length of all the sides of a shape added together.

So to find the third side, we would subtract 9 and 18 from 49

49 - (9 + 18) = 22

The length of the third side is 22m.

For every possible angle $x$ , the fundamental law of trigonometric states that

$\sin^2(x)+\cos^2(x) = 1$

In your case, the inputs you provided would lead to

$\dfrac{16}{25}+\dfrac{25}{169} = \dfrac{3329}{4225} \approx 0.8 \neq 1$

So, it is not possible that, for a certain angle x, we have

$\sin(x) = \dfrac{4}{5},\quad \cos(x) = -\dfrac{5}{13}$
