Answer:
tan 5π/24.
Step-by-step explanation:
We use the identity:
tan (A - B) = (tan A - tan B) / (1 + tan A tan B)
so the first expression simplifies to
tan ( π/3 - π/8)
= tan 5π/24.
The correct answer is A. All triangles' interior angles equal 180.
You get 14/16 and when you simply you then get 7/8.
