To find t the hypotenuse we use sine

sin 53° = 14/t

t = 14/sin 53°

t = 17.53

Since we have both hypotenuse and the opposite we use Pythagoras theorem to find s

(17.53)² = 14² + s²

s = √17.53² - 14²

s = 10.55

t = 17.53 s = 10.55

Hope this helps.

$\\ \rm\longmapsto sin120$

$\\ \rm\longmapsto sin(90+30)$

$\\ \rm\longmapsto cos30$

$\\ \rm\longmapsto \dfrac{\sqrt{3}}{2}$

Now

$\\ \rm\longmapsto tan\left(\dfrac{2\pi}{4}\right)$

$\\ \rm\longmapsto tan135$

$\\ \rm\longmapsto -1$
