Jerrod found the hypotenuse of a right triangle with legs 3 ft and 1 ft. Is his answer correct?
c2 = 32 + 12
c2 = 9 + 1
c2 = 8
c = 8

No, he setup the Pythagorean theorem incorrectly.
No, he made an error finding the square root.
No, he subtracted 1 and 9 instead of adding.
Yes, he correctly calculated the length of the hypotenuse

Answer:

The answer is no he is not correct, here's why.

C) No, he subtracted 1 and 9 instead of adding.

Step-by-step explanation:

Jerrod has found the hypotenuse, with the legs of 3 ft and 1 ft, his process is:

[tex]c^{2}[/tex] = 32 + 12

[tex]c^{2}[/tex] = 9 + 1

[tex]c^{2}[/tex] = 8

c = 8

The legs Jerrod said are 3 ft and 1 ft

so A and B of the formula of pythagorean theorem could be:

[tex]a^{2}[/tex] = (3)[tex].^{2}[/tex]

[tex]b^{2}[/tex] = (1)[tex].^{2}[/tex]

This leads us to:

[tex]3^{2} + 1^{2} = c^{2}[/tex]

which is:

9 + 1 = [tex]c^{2}[/tex]

10 = [tex]c^{2}[/tex]

In this case, Jerrod had calculated wrong by instead of adding he had subtracted.

(I don't know where he got 32 + 12, but other than that his process is correct other than calculation error)

Answer:

c
