Tan(x) + tan(y)/1 - tan(x)tan(y) = sin(x)cos(y) + cos(x)sin(y)/cos(x)cos(y) - sin(x)sin(y)
tan(x + y) = sin(x + y)/cos(x + y)
tan(x + y) = tan(x + y)
Answer:
Step-by-step explanation:
A gunner fires 10 bullets at a target, with the probability of hitting the target at each shot is p = 0.8. Know that, if all 10 bullets hit the target, the target is definitely destroyed. If 2-9 bullets hit the target, the target is destroyed with a probability of 80%. If only 1 bullet hits the target | then the target is destroyed with a probability of 20%. What is the probability that the target is destroyed?
ABD = ABC + CBD
So 6x + 27 + 7x - 9 = 96
Now we need to isolate x
13x + 18 = 96
13x = 88
x = 6
And then apply x to the angle we need to find ( CBD )
CBD = 6x + 27
CBD = 6(6) + 27
CBD = 36 + 27 = 63
Angle CBD = 63°
55/4 would be 13.75.
So each person would get $13.75.
