Both triangles are similar because of angle angle similarity.

So you can just make a proportion.

\frac{CB}{BA} = \frac{FE}{x}

Insert the numbers:
\frac{30}{35} =  \frac{15}{x}

Cross multiply: 30x = 520
x = 17.5

Answer:

n = 8

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Left to Right

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

6n + 7 = 55

<u>Step 2: Solve for </u><em><u>n</u></em>

  1. Subtract 7 on both sides:                    6n = 48
  2. Divide 6 on both sides:                       n = 8

<u>Step 3: Check</u>

<em>Plug in n into the original equation to verify it's a solution.</em>

  1. Substitute in <em>n</em>:                    6(8) + 7 = 55
  2. Multiply:                               48 + 7 = 55
  3. Add:                                     55 = 55

Here we see that 55 does indeed equal 55.

∴ n = 8 is a solution of the equation.
