If the length of the legs of a right triangle are 5 m and 7 m, what is the length of the hypotenuse?

irakobra [83]

Answer:

$c = 8.60232526704263$

$c \approx8.6$

Step-by-step explanation:

${c}^{2} = {a}^{2} + {b}^{2}$

$c = \sqrt{ {a}^{2} + {b}^{2} }$

$c = \sqrt{ {5}^{2} + {7}^{2} }$

$c = \sqrt{25 + 49}$

$c = \sqrt{74}$

$c = 8.60232526704263$

$c \approx8.6$

Since the exponent of the scientific notation is positive, move the decimal point 6 places to the right.

1620000

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps :)
