4. The length of a man's shadow is directly proportional with his height. At the same time of day, a man who is 1.8 meters tall casts a 25.2 meter shadow and his son casts a 21 meter shadow. What is the height of the man's son, in meters? If necessary, round to the nearest tenth.

step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

is should be y = 5x

correct me if im wrong
