Find the value of h rounded to the nearest tenth

3241004551 [841]

For angle G, FH is the opposite leg.
h is the hypotenuse.

The trig ratio that relates the opposite leg and the hypotenuse is the sine.

$\sin \theta = \dfrac{opp}{hyp}$

$\sin 48^\circ = \dfrac{5}{h}$

$h = \dfrac{5}{\sin 48^\circ}$

$h = 6.7$
