<u>Answer:</u>
The correct answer option is C. .
<u>Step-by-step explanation:</u>
We are given an equilateral triangle which is divided into two equal halves and that makes two right angled triangles with known measures of angles.
We are to find the length of the altitude of the triangle. For that we can use the trigonometric ratios.
Therefore, the correct answer option is C. .

For this case we have the following function:
We change the variables:
From here, we clear the value of y.
Then, we make the following change:
Finally, the inverse function is:

(5) Graph:
(6) Solutions: (-1, -5) and (-2, -7)
Not solutions: (1, 1) and (-4, -3)
EXPLANATION
(5) To graph this system, first, we have to graph each of the inequalities. Both are linear, so we have to graph each line with a dashed line - this is because they are "less than" the line, so the line is not included, and shade the area below each of them.
The first inequality is y < -3x-4,
The second inequality is y < 2x - 1,
The graph of the system is the area shared by both graphs,
(6) Any point that is inside the shaded area is a solution of the system. For example, points (-1, -5) and (-2,-7) are solutions to the system.
On the other hand, any point outside that area, or on the dashed lines is not a solution. For example, points (1, 1) and (-4, -3) are not solutions
