The 3 inside angles of a triangle need to equal 180 degrees.

Add the 3 together to equal 180:

X + 2x + x+ 14 = 180

Combine like terms:

4x + 14 = 180

Subtract 14 from both sides:

4x = 166

Divide both sides by 4

X = 41.5

Answer:

Fraction form: x = 83/2

Decimal form: x = 41.5

Step-by-step explanation:

The 3 angles inside the triangle will always add up to 180 degrees.

So that gives us the equation:

x + 14 + x + 2x = 180

Combine like terms:

4x + 14 = 180

Subtract on both sides:

4x = 166

Divide:

41.5
