The angle is 60° because
B is a right angle and that adds to 90°, so dividing 90 by 3 would get 30
30 x 2 = 60
and to check the answer
x = 30
A=30
B=90
C=60
this adds to 180 which is correct because the angles in a triangle add to 180° :)
Marbles in a bag: 3 green, 4 yellow, 5 blue, 8 pink.
Event A - get a green or yellow marble
Event B - get a pink marble
Events A and B are independent because we draw a marble from a bag with 20 marbles in both cases.

Probability of combined events is
Answer:
One solution
Step-by-step explanation:
We know there is only one solution because the lines do not have the same slope, nor are they the exact same line.
So we know they must have just one solution.
Best of luck
Answer:
9.) The slope is 3 and the y-intercept is -5
10.) y = 0.25x -11
