Question

What is the value of the angle marked with x?

**Question: What is the value of the angle marked with \( x \)?** The image displays a diagram of a quadrilateral with one angle marked as \( 48^\circ \) and another angle marked as \( x \). The sides of the quadrilateral are labeled with the following lengths: - 10.5 units (adjacent to the \( 48^\circ \) angle) - 20.1 units (top side, opposite to the 10.5 units side) - 9.9 units (side next to the \( x \) angle) - 21.0 units (bottom side, opposite to the 9.9 units side) The quadrilateral appears to be a trapezoid given the markings of the sides. The problem asks for the value of the angle \( x \) in the diagram. To find the value of \( x \): 1. Determine if there are any properties or theorems applicable (such as the sum of interior angles in a quadrilateral is always \( 360^\circ \)). 2. Utilize the given angle and properties of the figures involved, such as a trapezoid or parallelogram, to solve for \( x \). **Note:** - Ensure students understand the geometry and trigonometry concepts required to solve for the angle \( x \). - Encourage the use of diagrams and labeled angles to aid in visualization and comprehension of the problem. \( \boxed{ }\)
