As we are given with
we are supposed to simplify this expression. which can be done as below
It would be C!!!!!!!!!!!!!!!!!!!!!!!!!
The answer is y-x because there are y seats and x people leave and the key word is leave. When there is words like leave or less those give you hints that mean you are subtracting.
Solution
Here the angles of the right triangle is 30, 60 and 90.
We are given ∠a = 30 degrees.
A triangle with angles 30, 60 and 90 degrees has the property that the lengths of the sides of a 30-60-90 triangle are in the ratio 1:2:√3.
Given: 12√3 = ab
Therefore, the length of the AC = 2 * 12 = 24 .
The answer is 24.
