Question

I just this one please someone help

Answer 1

Answer:

100

Step-by-step explanation:

because 4, 3, and 2 all make 180 and 4 and 2 are both 40 so you add that which makes 80 and then you take 180 and subtract 80 which gives you 100

Answer 2

Answer:

100

Step-by-step explanation:

This is because angle 1 and angle 2 are congruent, so both of them are 40 degrees. To find angle 3, you do 40+40 which is 80. You then subtract 180-80=100. This is because angles 1, 2, and 3 are all on 1 straight line.
