ABC is a triangle with sides AB = 6m, BC =8m, and AC = 10m. A line k in the plane of the triangle ABC moves along the segment AC at the rate of 1cm per sec. The line starts at A and ends at C and is always perpendicular to AC.
1. How long does it take the line to reach the point B?
2. How long does it take the line to bisect the area of the triangle?
3. What is the area of the region that the line sweeps in its movement after 6min 45 sec?
4.What is the area of the region that the line sweeps at any give moment from the start of its movement?

Best ResponseYou've already chosen the best response.0ok so it is a right angle triangle, you can tell from the dimension. 6, 8, 10

Best ResponseYou've already chosen the best response.0ok so for 3, you have 6*60+45=405seconds, and times cm per second you get 405 cm convert to meters. 4.05 meters, (6^24.05^2)^1/2= you get the third side= 4.427 area of triangle= 0.5*4.426*4.05=8.96

Best ResponseYou've already chosen the best response.0thats wrong cause its a trap after 3.96 so if its 4.05 its a trapu cant use traingle formua

Best ResponseYou've already chosen the best response.0then for 2, i think you have to relate the triangle at the top, with the one at the bottom interms of areas, and in terms of lengths and solve the 2 equations with 2 unknowns

Best ResponseYou've already chosen the best response.0iight, i g2g hopefully you can figure it out on your own, if not maybe other ppl will be able to help but i gotta go. sorry
