Step-by-step explanation:
A and B are along a straight line
(3x - 20) + 2x = 180
5x = 200
x = 40
3(40) - 20 = 100°
The answer you chose in the photo is correct !!
Answer:

Answer:
2/3
Step-by-step explanation:
List all the possible sums. If it helps, make a table:
There are 36 total possible sums. Of those, 18 are even, and 6 are odd but multiples of 3.
Therefore, the probability is:
P = (18 + 6) / 36
P = 24 / 36
P = 2 / 3
