Question

answer attempt 2 out of 2
$x = 7.625$

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of interior angles of a triangle is 180°. So, 49°+(8x - 11)°+30° = 180°.

Step2: Simplify the left - hand side

Combine like terms: (49 - 11+30)+8x=180, which gives 68 + 8x=180.

Step3: Isolate the variable term

Subtract 68 from both sides: 8x=180 - 68, so 8x=112.

Step4: Solve for x

Divide both sides by 8: x = \frac{112}{8}=14.

Answer:

14
