Use the law of sines....
sin51/x=sin90/67
x=(67sin51)/sin90
x=52.07
....
tan39=(h-1.8)/44
h-1.8=44tan39
h=44tan39+1.8
h=37.4 m
<span>You take the probability of success (and the revenue generated by it) and the probability of failure (and the cost associated with trying it) and get an expected value:
aP(a) + bP(b)

Answer:
x=-5/3
Step-by-step explanation:
ABD + DBC = ABC
Substitute the values
6x+9 + x+1 = 10x+15
Combine like terms
7x+10 = 10x+15
Subtract 7x from each side
7x-7x+10 = 10x-7x+15
10 = 3x+15
Subtract 15 from each side
10-15 = 3x+15-15
-5 =3x
Divide each side by 3
-5/3 =x
This will give us a negative value for DBC
DBC = -5/3 +3/3 = -2/3
We cannot have a negative value for an angle
Check the values given.
