Answer:
[tex]\huge\boxed{\bf\:tan \: Z= \frac{4}{3}}[/tex]
Step-by-step explanation:
We know that, tan θ = opposite side of ∠θ / adjacent side of ∠θ.
Here, we need to find tan Z,
In this triangle for ∠Z,
- Opposite side = 28
- Adjacent side = 21
Then,
tan Z
= opposite side / adjacent side
= 28 / 21
= 4 / 3
