I'd be more than happy to help. Im a sophmore and Love math
we have to firstly apply the distance formula to find the length of sides of the triangle
distance formula =
So length AB =
BC=
AC =
Now perimeter = AB+BC+AC =
Plug in calculator
perimeter= 11.4 units
Well we know that total percentages always equals 100 so x + 45 = 100. You should get x = 55%
A = 1/2(17 + 27) (4)
A = 1/2(44)(4)
A = 88
answer
88
Answer: 3/4
