Mathematics
1 answer:
Scilla [17]3 years ago
3 0

Answer:

h = 21.2 cm

Step-by-step explanation:

You know the measure of one acute angle. It is 23 deg.

For that acute angle, the 9-cm leg is the opposite leg, and the h-cm leg is the adjacent leg. The trig ratio that relates the opposite leg to the adjacent leg is the tangent.

\tan A = \dfrac{opp}{adj}

\tan 23^\circ = \dfrac{9}{h}

h \tan 23^\circ = 9

h = \dfrac{9}{\tan 23^\circ}

h = \dfrac{9}{0.4245}

h = 21.2

Answer: h = 21.2 cm
