Given that the diagram shows the location of John and Mark in relationship to the top of the building labeled A, then:
a]
∠4 is the angle of elevation as seen by Mark from his location. It is the angle between the horizontal and the line from the object to the observer's eyes.
b]
∠3 is the angle of depression and it is congruent to the angle 5, which is the angle of elevation as seen by John from his location.
Answer:
A.)
Step-by-step explanation:
The answer that you had chosen is correct, because the number line is stating that you are subtracting 5 from 0, giving you -5. Then it is saying that you are subtracting 2 from that, giving you -7.
B.) is wrong, because they are adding the answer of the correct equation with another number, which would equal -12.
C.) is incorrect, because when you are adding a positive with a negative, you are actually subtracting, not adding. When you are doing this, always keep the sign for the answer (negative or positive) with whatever the larger addend is. So in this letter's situation, the equation would look like this: -5 + 2 = -3.
D.) is incorrect because once again, they are taking the original correct answer and subtracting it from another number, which would be -12.
I hope this helps.
