Answer:
= 2√53 ≈ 14.56 ; = √101 ≈ 10.05 ; = √41 ≈ 6.40 ;
Step-by-step explanation:
A(8, –8), B(6, 8), C(2, 4)
= = (7, 0) ;
midpoint of BC = [(6 + 2)/2, (8 + 4)/2] = (4, 6) ;
midpoint of AC = [(8 + 2)/2, (- 8 + 4)/2] = (5, - 2) ;
= = √41 ≈ 6.40
= √[(4 - 8)² + (6 + 8)²] = 2√53 ≈ 14.56
= √[(5 - 6)² + (- 2 - 8)²] = √101 ≈ 10.05
= 2√53 ≈ 14.56 ; = √101 ≈ 10.05 ; = √41 ≈ 6.40 ;
