Question

Quadrilateral MNPQ, given that MN = 5.5cm, NP = 4.5cm, ∠M=90°,∠N=90°, ∠P=120°

Answer 1

Answer:

Add the two known angles of the quadrilateral with the new angle. For example if your quadrilateral had the angles 45, 40, and 115 degrees, you would get a sum of 200 degrees (45 + 40 + 115 = 200). Subtract the sum of the three angles from 360, to get the final angle.
