Given:
The figure of a right triangle ABC.
To find:
The trigonometric ratios 
.
Solution:
Using Pythagoras theorem,
Taking square root on both sides.
So, measure of BC is 8 units.
Now,
Similarly,
And,
Therefore, the required trigonometric ration are 
.
The answer should be true
Answer: the last option.
A binomial experiment is an experiment with only two possible outcomes.
In the first option, there is three possible outcomes (i.e. A, B, C)
In the second option, there is four poissible outcomes (i.e. ace, king, queen, jack)
The third option has six possible outcomes (i.e. six faces of a die)
In the last option, there are two possible outcomes (i.e. '2 number cubes')
