Answer:
x = 8
Step-by-step explanation:
Since we know that the 2 triangles are similar (AA Similarity), we find the ratio of Triangle PLM: 2
We then multiply 4 by 2 (the ratio) to get x = 8 as length JK.
Set up a proportion here as the height over the shadow of the adult = to the height over the shadow of the baby. so you have 12/4.8 = height/2. cross multiply to get 12*2=4.8 times height, which is 24 = 4.8*height. divide both sides by 4.8 to get height = 5 feet
1) yes
2) x=-4,y=-7
3) x= -3, y=4
4) x= -1, y=2
5) x= -5, y=-8
