Tolong dibantu ya kak

Bangun Ruang

Diketahui:
AB = 12 cm
BC = 10 cm
TC = 13 cm
Ditanya:
a) TE = ?
b) TO = ?

Jawab:
a) TE^2 = TC^2 - CE^2
TE^2 = 13^2 - (BC/2)^2
TE^2 = 169 - 5^2
TE^2 = 169 - 25
TE^2 = 144
TE = √144
TE = 12 cm.

b) TO^2 = TE^2 - EO^2
TO^2 = 12^2 - (AB/2)^2
TO^2 = 144 - 6^2
TO^2 = 144 - 36
TO^2 = 108
TO = √108
TO = √36 x 3
TO = 6√3 cm.

*semoga membantu. sukses selalu ^_^
