bantu ya?? bagi yang tau okey(:

a.
EG² = FG² + GH²
EG² = 10² + 10²
EG² = 100 + 100
EG² = 200
√(EG²) = √200
EG = √(100 × 2)
EG = 10√2

AG² = AE² + EG²
Karena AE = BF, maka:
AG² = BF² + EG²
AG² = 10² + (10√2)²
AG² = 100 + 200
AG² = 300
√(AG²) = √300
AG = √(100 × 3)
AG = 10√3


b.
EG² = FG² + GH²
EG² = 5² + 5²
EG² = 25 + 25
EG² = 50
√(EG²) = √50
EG = √(25 × 2)
EG = 5√2

AG² = AE² + EG²
Karena AE = BF, maka:
AG² = BF² + EG²
AG² = 10² + (5√2)²
AG² = 100 + 50
AG² = 150
√(AG²) = √150
AG = √(25 × 6)
AG = 5√6
