Question

In AABC, the measure of ZB=90°, AC = 50,

CB = 30, and BA = 40. What ratio
represents the tangent of ZA?
Help ASAP please!!!!

Answer 1

tanA = 3/4

General Formulas and Concepts:

Trigonometry

• tan∅ = opposite over adjacent

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

1. Substitute: tanA = 30/40
2. Simplify: tanA = 3/4

And we have our final answer!
