Question

what is m∠1? 93° 47° m∠1 = °

Explanation:

Step1: Recall exterior - angle property

The exterior - angle of a triangle is equal to the sum of the two non - adjacent interior angles.

Step2: Identify non - adjacent interior angles

The non - adjacent interior angles to $\angle1$ are $93^{\circ}$ and $47^{\circ}$.

Step3: Calculate $m\angle1$

$m\angle1=93^{\circ}+47^{\circ}=140^{\circ}$

Answer:

$140$
