Slope of AB=(2-3)/(1+1)=-1/2; AC=(-1-3)/(-3+1)=-4/-2=2; BC=(-1-2)/(-3-1)=-3/-4=3/4.
The product of two sides that are perpendicular is -1. Slopes of AB and AC are perpendicular so angle A is a right angle. ABC is a right-angled triangle.
I also think its 4 but im not sure
Answer:
17
Step-by-step explanation:
Pythagorean formula
a²+b²=c²
in other words, sidea²+sideb²=hypotenuse
8²+15²=c²
64+225=c²
289=c²
√289=√c²
17=c
