A Texas rancher wants to fence off his four-sided plot of flat land. He measures the first three sides, shown as A, B, and C in Figure 3.27,
where A = 4.05 km and Oc = 19°. He then correctly calculates the length and orientation of the fourth side D. What is his result?
D =
km
OD =

Figure 3.27
Alishba wakes up late and runs to school, covering a distance of 2.55 km in a direction of [N200 E] as measured from her home. She then realizes that her friend Lydia has her homework and races over to his house 0.5 km away [W] from the school. The two friends then decide it’s not worth going to class late so they go off to the mall that is 2.8 km [W500 S].
a) What is Alishba’s total displacement?
b) If the total time taken by Alishba to run to school then over to the friend’s house was 25 minutes, what was her average velocity?
Light speed c = 3.0* 108 m/s.
A light year is a distance light travels in one year.
Calculate a light-year in

What isthe elevation of the UFO? Round your answer to the nearest thousandth mile. Part (B). Now, one of your radar stations is broken. So you have only one radar. The workingradar suddenly detects another UFO. According to the data provided, the angle of elevation of the UFOfrom some point A on the ground is 60 degrees.After flying 15 seconds horizontally, the angle of elevationchanges to 30 degrees.Also, it is detected by your working radar that the UFO is flying at a speed of 200 m/s,can you find the elevation (height) at which the UFO is flying?Round your answer to the nearest thousandth meter.arrow_forward
