Question

Transcribed Image Text:The image shows a trapezoid with labeled angles: \(a\), \(b\), \(c\), and \(d\). The problem states:
"If angle \(c\) measures \(4x\) degrees, and angle \(b\) is 168 degrees, what is \(x\)?"
Below the problem, there is a box for the answer.
### Explanation
In the diagram, angles are labeled in a quadrilateral shape, specifically a trapezoid. The angles are denoted by letters:
- Angle \(a\) is the upper left angle.
- Angle \(b\) is the upper right angle, measuring 168 degrees.
- Angle \(c\) is the bottom right angle, given as \(4x\) degrees.
- Angle \(d\) is the bottom left angle.
The task is to find the value of \(x\) given these conditions.
### Solution Tip
Remember that the sum of the interior angles in a quadrilateral is always 360 degrees. This information can be used to write an equation involving the given angle measures to solve for \(x\).
