Step-by-step explanation:

tan 23= 9/h

0.4245= 9/h

h=9/0.4245

h= 21.2

Answer:

h ≈ 21.2 cm

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{9}{h}[/tex] ( multiply both sides by h )

h × tan23° = 9 ( divide both sides by tan23° )

h = [tex]\frac{9}{tan23}[/tex] ≈ 21.2 cm ( to 1 dec. place )
