# Is right?

Determine whether the triangle with legs (catheti) 19.5 cm and 26 cm and length of the hypotenuse 32.5 cm is rectangular?

Result

x =  1

#### Solution:

$a=19.5 \ \text{cm} \ \\ b=26 \ \text{cm} \ \\ c=32.5 \ \text{cm} \ \\ \ \\ c_{1}=\sqrt{ a^2+b^2 }=\sqrt{ 19.5^2+26^2 }=\dfrac{ 65 }{ 2 }=32.5 \ \text{cm} \ \\ c=c_{1} \ \\ \ \\ x=1$
