x = 17

Step-by-step explanation:

1. First, we should know that all angles in any triangle add up to 180°.

This means that x + 17 + 6x + 10 + 4x - 34 = 180

2. (Solving)

Step 1: Simplify both sides of the equation.

(x+6x+4x)+(17+10-34)=18011x -7 = 180

Step 2: Add 7 to both sides.

11x - 7 + 7 = 180 + 711x = 187

Step 3: Divide both sides by 11.

\frac{11x}{11} =\frac{187}{11}x = 17

Step 4: Check if solution is correct.

(17)+17+6(17)+10+4(17)-34=18017 + 17 + 102 + 10 + 68 - 34 = 180214 - 34 = 180180 = 180

Therefore, x = 17.

x=17

Reasoning:

The three interior angles of a triangle will always have a sum of 180°. Thus, you could make an algebraic equality with this information.

6x+x+4x+17+10-34=180

11x-7=180

11x=187

\frac{11x}{11} =\frac{187}{11}

x=17
