Answer:
A. 47.3°
Explanation:
The sum of all the angles in a triangle equals 180°, so we need to subtract 42.7° and 90° from 180° to get ∠N.
180° - 90° - 42.7° = 47.3°
∠N = 47.3°
47.3
A triangles angles add up to 180 degrees
At 42.7 and 90 and you get 132.7
Subtract 132.7 from 180 and you get 47.3 degrees.
