Question

ERROR ANALYSIS Describe and correct the error in finding m<1

Answer 1

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 &=180^(\circ)\\\\154^(\circ)+m \angle1 & = 180^(\circ)\\\\m \angle1 & = 26^(\circ)\end{aligned}}`
