Answer:
4743246
Step-by-step explanation:
Okay so process of elimination. The first option isn't correct because the sum of the interior angles for any triangle is always 180 degrees. x would be 25 degrees for ABC because 90+65=155 and 180-155=25. Y would be 95 degrees for DEF because 65+20=85 and 180-85=95, so y does not equal 90 degrees. For B, No side lengths are given. C is also not the correct answer so the answer is D. I can link you to another brainly post that has the same question or a similar with an explanation on determining the answer if you'd like :)
Given two reference points, we want to answer some questions, the answers are:
- a) The 0 should represent the surface of the water of the pool.
- b) The slide is 12 ft above the zero (12ft above the surface of the water)
- c) She should mark the pole with a -4 on the number line.
So we start with two reference points:
- -8, which represents the depth of water in the swimming pool.
- 12, which represents the height of the slide at the pool.
So positive numbers represent height, negative ones represent depth.
A) Here the 0 should represent the surface of the water of the pool.
B) on this situation, we should see that the slide is at 12, meaning that is 12 ft above the surface of the water in the pool.
C) The pole is at a depth of 4 ft, and 0 represents the surface, then -4 will represent the depth of the pole when it is at a depth of 4 ft. She must mark the level of the pole as a -4 on the number line.
