Answer:
angle 1: 30
angle 2: 41
angle 3: 96
Step-by-step explanation:
So the angles' sum in one triangle is 180 degrees so you know two of the first triangle's angles so you sum them up and you get: 150 so now you subtract that from 180 and get 30.
Now you can see that if you want to get angle 2 you need to get angle 3 first. so you can see that the 84 degrees is on the same line as angle 3 so, we also know that a line is 180 degrees. so 180-84=96.
Now to get angle 2 we just simply sum up 43 and 96 which is 139, then we subtract that from 180, then we get 41.
