Hey there :)
We need to use trigonometry here
Given is the angle = 30°
And one side = 26
With a missing side = x
The missing side is the opposite of the given angle, we have the adjacent but we don't know the value of the hypotenuse, so we need to use Tangent
Tan α =
tan 30 =
26tan(30) = x
x = 15

Answer:
Therefore the probability of getting both blue marbles is .
Step-by-step explanation:
Probability : The ratio of favorable outcomes to the total outcomes.
Given that a bag contains 7 marbles which are red in color, 2 marbles which are blue in color and 3 marbles which are green in color.
Total number of marbles = (7+2+3) = 12
The probability of getting a blue on first drawn is
Now the number of blue marbles = (2-1)= 1 [ since 1 blue marbles is drawn]
Total number of marbles = (12-1) =11
The probability of getting a blue marble on second drawn is
Therefore the probability of getting both blue marbles is
