Answer 1

Answer:

multiply the amount that you have in the Polynesian country 87inches 37 to a quarter in t76

Answer 2

Answer:

2a square

Step-by-step explanation:

b = AC

c = AB

a = BC

let say BM is media on AC

and CN is median on AB

AM =CM = AC/2

AN = BN = AB/2

as median are perpendicular

BC^2 = BM^2 + CM^2

BC^2 = CN^2 + BN^2

adding both

2BC^2 = BM^2 + CM^2 + CN^2 + BN^2

2BC^2 = BM^2 + (AC/2)^2 + CN^2 + (AB/2)^2

2BC^2 = BM^2 + (AM)^2 + CN^2 + (AN)^2

2BC^2 = AB^2 + AC^2

2a^2 = c^2 + b^2
