Question

1)Determinati lungimea ipotenuzei unui triunghi dreptunghic isoscel cu cateta de:
a) 8 cm;
b) 9√2 cm;
c) x cm.

Answer 1

a) ipotenuza=√(8²+8²)=8√2
b) ipotenuza=√[(9√2)²+(9√2)²]=√324=18 cm
c) ipotenuza=√(x²+x²)=x√2

Answer 2

a)ipotenuza=$\sqrt{64+64}= \sqrt{128}$=8$\sqrt{2}$
b)ipotenuza=$\sqrt{162+162}= \sqrt{324}=18$
с)ipotenuza=$\sqrt{ x^{2} + x^{2} }= \sqrt{2 x^{2} } =x\sqrt{2}$
