Question

what is the value of u? u = submit

Explanation:

Step1: Find the adjacent interior angle

Adjacent angles on a straight line sum to \(180^{\circ}\). So, the interior angle at \(E\) is \(180^{\circ}- 136^{\circ}=44^{\circ}\).

Step2: Use the property of isosceles triangle

Since the triangle has two equal - marked angles (at \(E\) and \(D\)), it is isosceles. So, the interior angle at \(D\) is also \(44^{\circ}\).

Step3: Calculate \(u\)

The sum of angles in a triangle is \(180^{\circ}\). So, \(u = 180^{\circ}-44^{\circ}-44^{\circ}=92^{\circ}\).

Answer:

\(92\)
