<span>Vertical angles must be C and D
A.be complementary. They are not always complementary, to be complementary means having a sum of 90 deg
B.be acute. - Vertical angles can be NOT acute depending on how they are positioned and intersected with the lines.
Answer
C.have the same vertex.
D.be congruent.</span>
Given that the two right triangles are congruent, there are two possibilities.
9x - 15 is equal to the angle 33° or 9x - 15 is equal to the other angle of the first triangle.
Let's probe with the first option:
9x - 15 = 33 => 9x = 33 + 15 = 48
=> x = 48 / 9 = 5,33, which is no in the list of options.
Now, let's probe the second option.
The other angle of the first right triangle is 90° - 33° = 57°
Then, 9x - 15 = 57
=> 9x = 57 + 15 = 72
=> x = 72 / 9 = 8
Which is the option c. 8.
So, I am sure that if you have a figure it will be compatible with that answer, else yet the procedure to find the answer is what I have used here.
Answer: option c. 8
The tower is 14 meters high.
Please mark as brailiest answer if you can.

Answer: D) Cannot be determined</h3>
Explanation:
Choice A isn't the answer because we don't know anything about the angles, so we can't use the AA (angle angle) Similarity theorem.
Choice B isn't the answer because we don't have info about all three pairs of sides (we only have two pairs of sides).
Choice C isn't the answer in a similar way choice A isn't either. We don't know anything about the angles, so we can't use the "A" in "SAS".
Choice D is the only thing left. It turns out we don't have enough info to be able to determine if the triangles are similar or not.
