Question

on your own: exterior angles of a trenter your answer in the box.$x = \square$

Explanation:

Step1: Apply exterior angle theorem

The exterior angle of a triangle equals the sum of the two non-adjacent interior angles, so:
$$7x + 3 = 85 + 50$$

Step2: Simplify the right-hand side

Calculate the sum of the two angles:
$$7x + 3 = 135$$

Step3: Isolate the term with x

Subtract 3 from both sides:
$$7x = 135 - 3$$
$$7x = 132$$

Step4: Solve for x

Divide both sides by 7:
$$x = \frac{132}{7} \approx 18.86$$

Answer:

$x = \frac{132}{7}$ (or approximately 18.86)
