We are given with
arc AC = 130
The measure of the arc on the other side of the circle is
360 - 130 = 230
Therefore, according to the theorem on circles, the measure of angle ABC is
(1/2) ( 230 - 130) = 50
Answer:

Step-by-step explanation:
Given: Let A be the event that the first die lands on 2 and B be the event that the second die lands on 2.
To find:
P(A), the probability that the first die lands on 2
P(B), the probability that the second die lands on 2
P(A and B): the probability that the first die lands on 2 and the second die lands on 2
Solution:
Probability refers to chances of occurrence of some event.
Probability = number of favourable outcomes/total number of outcomes
Sample space = 
Total number of outcomes = 6
For P(A):
Number of favourable outcomes = 1
So,

For P(B):
Number of favourable outcomes = 1
So,

P(A and B) = 
Yes, A and B are independent events as happening of each of the event does not depend on the other.
So x is one number and x + 1 is another
1. x + x + 1 = 57;
2. 2x + 1 = 57;
-1 -1
4. 2x = 56
5. x = 56/2
6. x = 28
So, x + 1 = 28 + 1 = 29
So 28 and 29 are the 2 consecutive integers of 57
