statuscvo [17]

The answer is: [A]: "right [triangle]" .
________________________________________________
Explanation:
________________________________________________
Given: Side lengths:
________________________________________________
" 24 in., 32 in., and 40 in " ;
________________________________________________
Divide each side length by "8" ;

24 in. / 8 = 3 in. ;

32 in. / 8 = 4 in. ; and

40 in. / 8 = 5 in. .
_________________________________________________
3 in . , 4, in, 5 in. ; is a "right triangle" ;

since: 3² + 4² = 5² ;

→ 9 + 16 = 25 ;

according to the Pythagorean theorem: " a² + b² = c² " .

Answer:

$\large \boxed{27 \, \%} }$

Step-by-step explanation:

$\begin{array}{rcl}\text{Percent error}&= &\dfrac{\lvert \text{Measured - Actual}\lvert}{ \text{Actual}} \times100 \,\%\\\\& = & \dfrac{\lvert 10 - 13.75\lvert}{13.75} \times 100 \, \% \\\\& = & \dfrac{\lvert -3.75\lvert}{13.75} \times 100 \, \%\\ \\& = & \dfrac{3.75}{13.75} \times 100 \,\%\\\\& = & 0.27 \times 100 \, \%\\& = & \mathbf{27 \, \%}\\\end{array}\\\text{The percent error is $\large \boxed{\mathbf{27 \, \%} }$}$
