Answer 1

Answer: m∠F = 31°

Solution: The triangle's rotation is irrelevant to the measure of its angles. In other words, angles D, E, and F will all stay the same if the triangle is turned ("rotated"). That being said, we know by definition that the interior angles of a triangle add up to 180°. We are given two of the angles, and we are asked to find the third:

1. m∠D + m∠E + m∠F = 180°
2. 48° + 101° + m∠F = 180°
3. 149° + m∠F = 180°
4. m∠F = 31°
