Question

Ipoteza : triunghi dreptunghic
Triunghi DEF, m(unghi D) =90 grade
DE=24 cm
DF=18 cm
Concluzie : EF =?

Answer 1

Conform teoremei lui Pitagora=>
EF^2=DE^2+DF^2
EF=SQRT (DE^2+DF^2)=SQRT (24^2+18^2)=SQRT (576+324)=SQRT (900)=30cm
P.S. ^2-La puterea a 2-a
SQRT-Rădăcină /radical

Answer 2

$\it~\overset{\text{T.P.}}{\Longrightarrow} EF^{2} = DE^{2} + DF^{2} \\ \it EF^{2} = {24}^{2} + {18}^{2} \\ \it EF^{2} = 576 + 324 \\ \it EF^{2} = 900 \\ \it EF = \sqrt{900} \\ \it \boxed{EF = 30~cm}$
