In the triangle below, 21 = 35 and 3 = 100
vesna_86 [32]

Answer:

135

Step-by-step explanation:

Okay so we know that all angles in  tringle sums up to 180

Therefore ∠2 = 180 - ∠1 - ∠3 = 180 - 35 - 100 = 45deg

We also know that angles on a straight line add up to 180deg as well

Therefore ∠4 = 180 - ∠2 = 180 - 45 = 135deg
