What is the size of the missing angle? **extra**
120 degrees (6 - 2 = 4 triangles x 180 = 720. Sum of other = 90 + 90 + 130 + 140 + 150 = 600. 720 - 600 =120)
What is the size of the missing angle? **extra**
115 degrees (5 - 2 = 3 triangles x 180 = 540. Sum of other = 90 + 135 + 112 + 88 = 425. 540-425 =115)
