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
The quotient of a number and 15
Answer: B
Step-by-step explanation:
To find the result of the dilation, multiply each x and y coordinate by the scale factor, which in this case, is 1.5. I started out with the coordinate P, which had an original coordinate of (-2,1). In this case, I multiplied -2 by 1.5, and 1 by 1.5 to get (-3, 1.5). Since this is multiple choice, the only one with P as (-3, 1.5) is B, so we don't have to check the others.
Answer:3
The lines that are parallel have the same slope. For the line y=3x + 5, slope = 3, so, for parallel line slope also will be equal 3
