Answer:
<em>Approximate length of the side adjacent to ∠C is </em><em>7.66 inches.</em>
Step-by-step explanation:
*The appropriate triangle is attached below.
From the diagram, the right triangle ABC has
- Hypotenuse =


The side adjacent to angle C is BC. We can get the length of BC by applying trigonometric operations.
We know that,

Putting the values,

- Coordinates (x, y)
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = -7x + 6
y = -10x
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em> [1st Equation]: -10x = -7x + 6
- [Addition Property of Equality] Add 7x on both sides: -3x = 6
- [Division Property of Equality] Divide -3 on both sides: x = -2
<u>Step 3: Solve for </u><em><u>y</u></em>
- Substitute in <em>x </em>[2nd Equation]: y = -10(-2)
- Multiply: y = 20
You would plug in 6 where the x is so it would be -4 times 2 plus 5(6)
