Answer:
Angle D is complementary to angle A
Step-by-step explanation:
Complementary angles sum to 90 degrees.
Since angle is B is 90 degrees, the sum of angles A and D are also 90 degrees to make a straight line with an angle measure of 180 degrees.

Step-by-step explanation:
Answer:
Event A = white marble is selected
Event B = blue marble is selected
P(A) = 5/10 = 1/2
p(B) = 5/10 = 1/2
Probability that A and B are independent events is:
P(A∩B) = 1/2 × 1/2
Answer: 1/4
You can solve this by algebraically as well as graphically. When I tried both ways I got:
solution is x= -2<span />
