Answer: only (-1, -5)
Step-by-step explanation:
If x= -1 and y= -5
(-5)+5= 2((-1)+1)= 0
Answer:
BA ≈ 1.88
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Trigonometry</u>
- [Right Triangle Trig] sin∅ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use trig to find the missing length
<u>Step 2: Identify Variables</u>
<em>POV from angle C</em>
Angle = 28°
Adjacent = BA
Hypotenuse = 4
<u>Step 3: Solve for </u><em><u>BA</u></em>
- Substitute [sine]: sin28° = BA/4
- Isolate <em>BA</em>: 4sin28° = BA
- Evaluate: 1.87789 = BA
- Rewrite: BA = 1.87789
- Round: BA ≈ 1.88
