Question

A triangle has coordinates A(-5,0), B(1,5), and C(4,-2). Find BC, round to the nearest tenth if necessary for BC. PLEASE ANSWER ASAP!!!

Answer 1

BC = 7.6

Explanation:

Given the coordinate of a triangle A(-5,0), B(1,5), and C(4,-2), the length BC will be the distance between B and C and this is expressed using the formula;

D =√(x2-x1)²+(y2-y1)²

Given

B(1,5), and C(4,-2)

BC = √(4-1)²+(-2-5)²

BC = √3²+(-7)²

BC = √9+49

BC = √58

BC = 7.6 (to the nearest tenth)
