Answer 1

Step-by-step explanation:

write the equations of AB and AC by one point form as you know the co-ordinates of A and the slopes of Ac and Ab can be find out as products of slopes of perpendicular lines =-1 then by solving AB AND AC with given lines to get the co-ordinates where the given lines intersect ab and AC then by using distance formula find Band C

Answer 2

Answer:

Step-by-step explanation:

A coordinates are x=1 and y= -2

x+2y=0. X-y=5 simultaneously solve.

x=-2y,

-3y=5

y=-5/3

2y=-10/3

x= 10/3

midpoint of bc has x=1

10/3(3/10)=1

y(3/10) is y coordinates for b and c,

y for b and c = -1/2

x coordinates of midpoint of bc is 1

x coordinates of b and c is 2 ( inscribed triangle theorem)

hence, b  and   c  coordinates are (2,-1/2).
