Question

what is the value of u?

Explanation:

Step1: Use the property of right angle

Assume the two angles form a right - angle (\(90^{\circ}\)). Let \(u\) be one angle and \(31.9^{\circ}\) be the other.

Step2: Calculate \(u\)

We know that \(u + 31.9^{\circ}=90^{\circ}\). Then \(u = 90^{\circ}-31.9^{\circ}\).
