If the lengths of the legs in a right triangle are 7 and 8, what is the approximate length of the hypotenuse?

Question

If the lengths of the legs in a right triangle are 7 and 8, what is the approximate length of the hypotenuse?

A. 1.4
B. 3.8
C. 5.4
D. 10.8
Is the answer D?
Thanks

Answer 1

I agree with Brady. The correct answer is 10.6.

Answer 2

Well, it is still correct, even though when solved, it would be closer to 10.6 as the approximate value.

a^2 + b^2 = c^2

7^2 + 8^2 = c^2

49 + 64 = c^2

113 = c^2

10.630145812734649407999121914929 = c

10.630145812734649407999121914929 is closer to 10.6, but in this case 10.8 is correct.

I hope this helps! :)

Answer 3

it is 10.6 not 10.8

Answer 4

Yes, D is correct as long as the 8 is a 6. Was the 8 supposed to be a 6 instead?

Answer 5

No it says 8.

How did you get the 10.6 Brady?
