<span>The side opposite the 30 degree angle is half of the hypotenuse.
a^2 + b^2 = c^2 =>
a^2 + (c/2)^2 = c^2
12^2 + c^2/4 = c^2
4*12^2 + c^2 - 4c^2 = 0
576 - 3c^2 = 0
- 3c^2 = - 576
c^2 = 192
c = 8√3

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Z score is given by:
z = (raw score - mean) / standard deviation
Given that mean score is 76, and the standard deviation is 8.
For x > 90:
z = (90 - 76) / 8 = 1.75
P(z > 1.75) = 1 - P(z < 1.75) = 1 - 0.9599 = 0.0401

Answer:
Never will know:(
Step-by-step explanation:
If one basket is selected at random, the probability that both are mangoes is; 1/10
<h3>How to find probabilities?</h3>
Contents of first basket;
3 mangoes
4 oranges
3 apples
Contents of second basket;
5 mangoes.
5 oranges.
5 apples.
Probability of mango in first basket is = 3/10
Probability of mango in second basket is = 5/15
Thus;
Probability that both are mangoes = (3/10) * (5/15)
Probability that both are mangoes = 1/10
