tolong bantuin jawab yaa pake cara...

BC² = 6² + 8²
BC² =36 + 64
BC² =100
BC=√100
BC=10

BD² = 24² + 10²
BD² = 576 + 100
BD² =676
BD =√676
BD =26

Teorema Pythagoras

^ = pangkat

BC^2 = AB^2 + AC^2
BC^2 = 6^2 + 8^2
BC^2 = 36 + 64
BC^2 = 100
BC = √100
BC = 10 cm

BD^2 = CD^2 + BC^2
BD^2 = 24^2 + 10^2
BD^2 = 576 + 100
BD^2 = 676
BD = √676
BD = 26 cm (C).

*semoga membantu. sukses selalu ^_^
