Final answer:
To find the value of x in the triangle, we can use the fact that the sum of the angles in a triangle is always 180 degrees.
Step-by-step explanation:
To find the value of x, we can use the fact that the sum of the angles in a triangle is always 180 degrees. The given angles are 11.8°, 12.5°, and x. So, we can set up the equation: 11.8° + 12.5° + x = 180°. Solving for x, we have x = 180° - 11.8° - 12.5°. Evaluating this expression, x ≈ 155.7°. Therefore, the value of x is approximately 155.7°.
