Given the following angles:

2x

3x

(x + 12)

(2x + 4)

We know the sum of angle measures 360 degrees.

Thus, we have:

2x + 3x + x + 12 + 2x + 4 = 360

Let's solve for x:

Collect like terms

2x + 3x + x + 2x + 12 + 4 = 360

8x + 16 = 360

Subtract 16 from both sides:

8x + 16 - 16 = 360 - 16

8x = 344

Divide both sides by 8:


\begin{gathered} (8x)/(8)=\text{ }(344)/(8) \\ \\ x\text{ = 43} \end{gathered}

Therefore, the value of x is 43

ANSWER:

x = 43
