Answer: Option C

Explanation:

First,we know that all the angles in a triangle add up to 180 degrees.

Each triangle has 3 angles. Thus, we have the sum of three angles as shown:

180 = A + B + C

where we have angles A, B, and C. In our right triangle, one angle is 30 degree and we'll call that angle A. The other known angle is 90 degrees and we'll call this angle B. Thus, we have

180 = 30 + 90 + C

Simplify and solve for C.

180 = 120 + C

The area of a rectangular classroom is given as x² - 25.

To find the length and width of the room, we can look for factors of x² - 25 that can represent the length and width.

x² - 25 can be factored as the difference of squares:

x² - 25 = (x + 5)(x - 5)
