Question

1. what is x?

125°
x°
z°
70
180
55
125

Explanation:

Step1: Identify supplementary angles

The angle of \(125^\circ\) and \(x^\circ\) are supplementary, meaning their sum is \(180^\circ\).

$$125 + x = 180$$

Step2: Solve for \(x\)

Subtract \(125\) from both sides of the equation.

$$x = 180 - 125$$

$$x = 55$$

Answer:

55 (corresponding to the option with 55, assuming the options are labeled with their values, e.g., the third option if it's 55)
