Correct answer will be option A.
Two events are independent if the occurring of one event does not impact the occurring of the other event.
So this means, the knowledge of one event is having no impact on the probability of occurrence of the second event. Thus option A is correct
Answer:
Step-by-step explanation:
a^2 + B^2 = C^2
and all angle added together should make 180
the left box should be 20 and the right box should 17.321
Answer: 130
In order to solve for <4, you need to know that supplementary angles add up to 180°.
<3 = 50
180 - 50
130
**For future questions**
1. The sum of the interior angles of a triangle is 180°
2. Alternate interior angles are congruent
3. The exterior angle of a triangle is the sum of the nonadjacent interior angles

The answer is D, x = 3.
To find the answer to this, we need to solve for x.
4(x - 1) = 2(x + 1)
The first step is to either use the distributive property and get rid of the parenthesis or to divide each side by two. This shows division by two.
2(x - 1) = x + 1
Now we can get rid of the parenthesis
2x - 2 = x + 1
We want to get the numbers on one side and the variables on another
2x - x = 1 + 2
x = 3
