First,B bisects AC, this means that B dovids AC into two equal halves. therefore AB=AC
second and third steps are just isolating the terms containg y on one side of the equation and the other terms on the other side.
finally you have 3y=15, to get the value of y,you divide both sides of the equation by 3.
Answer:
Perimeter= 12 feet Area= 6 feet (squared)
Step-by-step explanation:
Perimeter= Adding all the sides together, that means it is 3+4+5= 12 feet
Area= Hight times base divided by 2. Because hight times base is area of a rectangle, and a right triangle (and all other triangles) is half of it. Because it is a right triangle, its hight must be 3 or 4, and base also 3 or 4. But no the same number twice, so 3*4=12, 12/2=6 feet (squared).
I hope that helped! =)
