Answer:
depending on which triangle
Answer:
21/3 i think
Step-by-step explanation:
There are two triangles: a small one to the left and a big one, which includes the small one. They both have a common angle (the leftmost angle) and since (we can assume) the two columns meet the floor at right angles, they both have two equal angles. This means they are similar (AAA).
Let the distance of the base of the stairs to the tallest column be d.
Because matching sides of similar triangles are in the same ratio,
4 / 6 = d / (6 + 12)
4 / 6 = d / 18
(4 * 18) / 6 = d
d = 12
The answer is C
Sorry I couldn't find this sooner!
The perimeter of any polygon means the sum of all the lengths of its sides. In this case the sides are (5x - 2), (2x - 3), and (4x + 3). We can find the perimeter by adding all of these lengths up:
(5x - 2) + (2x - 3) + (4x + 3)
= 5x - 2 + 2x - 3 + 4x + 3
=11x -2
Final Answer: B. 11x - 2
