Answer:
Last Option
Step-by-step explanation:
We have a triangle and we know its three sides.
We want to find one of your anguos. Then we use the cosine theorem.

Where

Now we solve for x from the equation

18=3+36x-50x-55
18=3-14x-55
18=-14x-52
70=-14x
x=-5

Answer:
The value is 
Step-by-step explanation:
From question we are told that
The number of types of marbles present jar is n = 3
Generally the probability of drawing a green marble is

Generally the probability of drawing a marble that is not green is

From the question we are told that there will be continuous drawing of marbles from the jar (in such a way that after each marble is drawn it is being replaced) until a green marble drawn
Let m be the number of times marbles has been drawn when a green marble was gotten
it then means that for m - 1 times the marbles where drawn a green marble was not obtain.
Generally the probability drawing m times is mathematically is mathematically represented as

=>
