Va rog Repede am nevoie de ea ​

Answer 1

a)

ΔAMC, ∡M = 90°

AM = MC              } => ΔAMC - isoscel dreptunghic

                              => AC = AM√2 = 3√2·√2 = 3·2 = 6 cm

Ab = AC²√3/4 = 36√3/4 = 9√3 cm²

b)

OC = AC·√3/2·2/3 = 6·√3·2/2·3 = 2√3 cm

MO = √MC² - OC² = √36 - 12 = √24 = 2√6 cm

V = Ab·MO/3 = 9√3·2√6/3 = 6√2 cm³

c)

MA = MC = MB

MA ⊥ MB ⊥ MC  } => VABC - regulat

OM = MV
