5. Triangle ABC has an angle of 90 degrees at B. Point A is on the y axis, AB is part of the line x-2y+8=0 and C is the point (6,2) (iii) Answer = AB equals the square root of 20 BC equals the square root of 20 Area of triangle equals 10 (iv) Using your answer to (iii), find the length of the perpendicular from B to AC. I don't even know where to start here, what is the method for figuring this out? And do they mean a line perpendicular to AC meeting B?
