Answer:
tanA = 3/4
General Formulas and Concepts:
Trigonometry
- tan∅ = opposite over adjacent
Step-by-step explanation:
Step 1: Define
Looking at ∠A, finding tangent
Step 2: Identify
opposite leg of ∠A = CB = 30
adjacent leg of ∠A = AB = 40
Step 3: Write ratio
- Substitute: tanA = 30/40
- Simplify: tanA = 3/4
And we have our final answer!
