Answer:
answer A. 0.5
Step-by-step explanation:
hello
as A and B are independent P(B/A)=P(B) =0.5
in short, the information provided by the event A does not impact at all the event B. so knowing A or not does not impact the probability of B.
you can use the formula as well P(B/A)=P(A and B) / P(A)=(P(A)xP(B))/P(A)=P(B)
hope this helps
Since the triangles are congruent, m<ACB = m<CAD = 2x + 8
m<B = m<D = 3x
m<CAB + m<B + m<ACB = 180
37 + 3x + 2x + 8 = 180
5x + 45 = 180
5x = 135
x = 27
m<CBA = m<B = 3x = 3(27) = 81
m<CBA = 81 deg
