Answer:

m∠1 = 26°

Explanation:

Interior angles of a triangle sum to 180°, not 360°.

Therefore, the correct calculations to find the measure of angle 1 are:


\boxed{\begin{aligned}115^(\circ)+39^(\circ)+m \angle 1 &amp;=180^(\circ)\\\\154^(\circ)+m \angle1 &amp; = 180^(\circ)\\\\m \angle1 &amp; = 26^(\circ)\end{aligned}}
