1.

AC^2 + AB^2 = BC^2 (t.Pitagora)

DE^2 = EF^2 - DF^2 (t.Pitagora)

2.

BC^2 = 12^2 + 9^2

BC^2 = 144 + 81

BC^2 = 225 =>BC=15

EF^2 = DF^2 + DE^2

EF^2 = 256 + 144

EF^2 = 400 =>EF=20

HI^2 = GI^2 - HG^2

HI^2 = 25^2 - 7^2 = (25-7)(25+7)

HI^2 = 18•32

HI^2 = 2 • 3^2 • 2^5 = 2^6 • 3^2

HI = 2^3 • 3

HI = 24

RQ^2 = RP^2 - PQ^2

RQ^2 = 250 - 169

RQ^2 = 81 =>RQ=9
