Answer:
bisecting a line segment
Step-by-step explanation:
We can immediately eliminate anything with an angle because there aren't any angles to bisect.
If we draw a line through the X points, it seems as though the line passes through the midpoint of . This, combined with the fact that the line segment through the X points is smaller than
by inspection, leads us to believe we are
.
Extra: Definition bank:
* Bisecting an angle: Constructing a line that "cuts" the degree of the angle in half.
* Bisecting a line segment: Constructing a line perpendicular to the original line that "cuts" the line in half(i.e. goes through the midpoint of that line).
* Copying an angle: Take the two lines that form an angle and constructing the same two lines with the same angle elsewhere.
* Copying a line segment: Constructing the same line segment elsewhere.
Answer:
1.5 nautical miles
Step-by-step explanation:
See the attached diagram.
The submarine starts to dive at point A and diving along AB.
If the distance traveled underwater i.e. AB = 1.7 Nautical miles and C is the point directly above its current position at B.
Then Δ ABC is a right triangle having ∠ BAC = 28° {Given}
So, using trigonometry we can write
⇒ nautical miles.
Therefore, the surface distance that the submarine travels is 1.5 nautical miles. (Answer)
