They are dependent events, because the probability of the second event depends on the result of the first event
If you replace the marble before picking up the second marble, then the first event didn't affect the second result ant the events were independent.
Given that you did not replace the marble, the second pick up has different probailities depending on the first result.

Answer:
x = 40
Step-by-step explanation:
because they are similar triangles
65+75 =140
180-140 = 40
B= 60
To find b you must do the pythagorean theorem because it is a right triangle
65^2 - 25^2=b^2
3600=b^2
60=b
x= 18
To find x you must know that a triangle is made up of 180 degrees.
x= 180-(72+90)
x=180-162
x=18
hope this helped :)
