Answer:

The answer is m∠1 = 72°

Step-by-step explanation:

One of the properties of a triangle is that all the angles of the triangle must add up to 180°.

Therefore:

m∠P + m∠O + m∠1 = 180°

Given that:

m∠P = 38° and m∠O = 70°

We can conclude that:

38° + 70° + m∠1 = 180°

m∠1 = 180° - 38° - 70°

m∠1 = 72°
