Question

Can someone please help me with this question?

Answer 1

BA ≈ 1.88

General Formulas and Concepts:

Pre-Algebra

• Equality Properties

Trigonometry

• [Right Triangle Trig] sin∅ = opposite over hypotenuse

Explanation:

Step 1: Define

We are given a right triangle. We can use trig to find the missing length

Step 2: Identify Variables

POV from angle C

Angle = 28°

Adjacent = BA

Hypotenuse = 4

Step 3: Solve for BA

1. Substitute [sine]: sin28° = BA/4
2. Isolate BA: 4sin28° = BA
3. Evaluate: 1.87789 = BA
4. Rewrite: BA = 1.87789
5. Round: BA ≈ 1.88
