Question

the diagram shows a triangle.
what is the value of u?
u = \square^\circ

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is \(180^\circ\).

Step2: Calculate \(u\)

Given two angles \(43^\circ\) and \(37^\circ\), so \(u = 180 - 43 - 37\).
\(u = 180 - (43 + 37) = 180 - 80 = 100\).

Answer:

\(100\)
