$(5x - 25)^{circ}$ $55^{circ}$

Explanation:

Step1: Set up linear equation

The angles form a straight line (180°), so:
$$(5x - 25) + 55 = 180$$

Step2: Simplify left side

Combine constant terms:
$$5x + 30 = 180$$

Step3: Isolate variable term

Subtract 30 from both sides:
$$5x = 180 - 30$$
$$5x = 150$$

Step4: Solve for x

Divide by 5 on both sides:
$$x = \frac{150}{5}$$

Answer:

$x = 30$
