For acute triangle XYZ below, can you find the tangent ratio of angle r°?

Answer:
Tan r = z/y
Step-by-step explanation:
Tangent = opposite / adjacent
Line XY, which is z, is opposite of angle r.
Line XZ, which is y, is adjacent to angle r.
The equation would be Tan r = z/y.
Answer: No, you can't find the tangent ratio of angle rº because the tangent ratio applies to any right triangle, and it applies to right triangles ONLY.
