Answer:
[tex]tan 56 = \frac{26}{x}[/tex]
Step-by-step explanation:
[tex]tangent = \frac{opposite}{adjacent}[/tex]
Side z is the hypotenuse, since it is opposite the right angle.
Side x is the adjacent, since it is next to the angle you are solving for.
The side measuring 26 is the opposite, since it is opposite the angle you are solving for.
