Answer:
(2,16)
Step-by-step explanation:
y=-x+18
y=8x
8x=-x+18
8x+x=9x
-x+x=0
9x=18
9x/9=x
18/9=2
x=2
y=8(2)
y=16

(essentially, it's the center of the triangle)
Answer:
Step-by-step explanation:
An isosceles triangle needs to have 2 congruent sides to be considered a isosceles triangle. To find the length of AB use Pythagorean theorem :
a^2+b^2=c^2
substitute the triangle's lengths which are given and you get:
3^2 + 3 ^2= c^2
simplify and you get
c= √18
Repeat for AC and you get the same thing: √18.
AB=AC=√18. The triangle is an isosceles triangle because you have 2 congruent sides.
