HELP DEF? it’s about to be twelve and this is the last question

Answer:
≈ 37.05 cm
Step-by-step explanation:
This is a right triangle, so we can use SOHCAHTOA to solve for x.
We should use tangent, as it involves all the given numbers on the triangle:
[tex]tan (39) = \frac{opposite}{adjacent}=\frac{30}{x}[/tex]
[tex]x=\frac{30}{tan(39)}=37.0469cm[/tex]
