I'm assuming this question is 3(1-4)(5-7)
3(-3)(-2)
-9(-2)
18
The first one is the answer I’m pretty sure
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.
