Answer to Problem 16RP
The coordinates of point Bare
Explanation of Solution
Given information:
ΔABD = ΔACD
The coordinates of point Aare
The coordinates of point C are
The coordinates of point Dare
Calculation:
It is given that, ΔABD = ΔACD
Both triangles have the same height, so their bases must be equal for their areas to be equal.
The base of ΔACD is 8.
Subtracting 8 from 6 gives the coordinates for B.
Point B lies on negative x −axis. The y coordinate of point B is 0.
The x coordinate is obtained by subtracting 8 from 6.
The coordinates of point Bare

- Can someone help me with this please?arrow_forwardMariela is in her classroom and looking out of a window at a tree, which is 20 feet away. Mariela’s line of sight to the top of the tree creates a 42° angle of elevation, and her line of sight to the base of the tree creates a 31° angle of depression. What is the height of the tree, rounded to the nearest foot? Be sure to show your work to explain how you got your answer.arrow_forward1arrow_forward
