Question

the diagram shows a triangle.
what is the value of u?
u = □°

Explanation:

Step1: Recall the sum of angles in a triangle

The sum of the interior angles of a triangle is \(180^{\circ}\). So, if the three angles of the triangle are \(50^{\circ}\), \(48^{\circ}\), and \(u\), then \(50 + 48+u=180\).

Step2: Solve for \(u\)

First, add \(50\) and \(48\): \(50 + 48=98\). Then, rewrite the equation as \(98 + u=180\). Subtract \(98\) from both sides: \(u=180 - 98\).

Answer:

\(82\)
