Question

een the two labeled angles.
uation to help you solve for x.
hint
you can either use your knowledge of vertical angles, or you could substitute x = 20
into the expression 7x.
enter the measure of the angle.
degrees

Explanation:

Step1: Identify the relationship

The angle \(7x^\circ\) and the \(140^\circ\) angle (assuming the \(1 - 0^\circ\) is a typo for \(140^\circ\)) are supplementary? Wait, no, looking at the hint, we substitute \(x = 20\) into \(7x\).

Step2: Substitute \(x = 20\) into \(7x\)

Calculate \(7\times20\).
\(7\times20 = 140\)

Answer:

140
