Question

1. round to the nearest tenth, if necessary. find the value of the missing sides. what is the m<y? ______

Explanation:

Step1: Recall triangle angle sum

In a right triangle, the sum of angles is \(180^\circ\), and one angle is \(90^\circ\). Given one acute angle is \(51^\circ\).

Step2: Calculate \(m\angle Y\)

\(m\angle Y = 180^\circ - 90^\circ - 51^\circ = 39^\circ\).

Answer:

\(39^\circ\)
