You are correct, it would be a reflection across the y-axis. I am great at visualizing but for those who are not (Not saying you) all they have to do is cut out a parallelogram and mimic the movements.
Answer:
B. Negative two-fifths (-2/5)
Step-by-step explanation:
1. Change the second number into a fraction if it isn't already.
2. Find the reciprocal of the divisor, or second fraction.
3. Multiply the numerators together.
4. Multiply the denominators together.
5. Simplify the answer if possible.
6. Determine if the answer is positive or negative using the sign rules.
Show your work:
-4/5 divided by 2/1
-4/5 divided 1/2
-4 * 1 = -4
5 * 2 = 10
Simplify:
-4/10 = -2/5
The specification of the problem includes a sketch of the relation between the towers showing two angles.
The sketch shows the segment of the track between the two towers (d), the heights of the two towers (954 feet and T), and the horizontal angles from the base of each tower to the top of the other tower.
Then you can write two trigonometric ratios.
1) From the triangle formed by the segment that separates the two towers, d, and the height of Sears Tower (T) with horizontal angle 27°:
tan (27°) = T / d => d = T / tan(27°)
2) From the triangle formed by the segment that separates the two towers, d, and the height of Comumbia Tower (954), with horizontal angle 53°
tan(53°) = 954 / d = > d = 954 / tan(53°)
Now you can equal the two equations => 954 / tan(53) = T / tan(27) =>
T = 954 tan(27) / tan (53) = 366.29 feet
Answer: 366.29 feet
