2x + 100 = 5x + 55
3x = 45
x = 15
2(15) + 100 = 130
180-130 = 50
so angle 2 is 50 degrees

Answer:
5/22
Step-by-step explanation:
A bag has 6 blue marbles, 4 red marbles, and 2 green marbles. Wo marbles are randomly chosen without replacement.
Total number of marbles =
6 blue marbles + 4 red marbles + 2 green marbles
= 12 marbles
The probability of picking a blue marble = P(B) = 6/12
Therefore, the probablilty that both marbles picked are blue without replacement is
= 6/12 × 5/11
= 30/132
= 5/22
