Aright triangle has a hypotensue of length 10 ft and one leg o length 7 ft. how long is the other leg? round the answer to the nearest tenth of a foot.

x = 7.1 to the nearest tenth.

Step-by-step explanation:

Hypotenuse = 10;

Opposite = 7; and

Adjacent = x

Pythagoras rule states that square Hypotenuse side is equal to square Opposite side Plus square Adjacent side, so we solve;

(hyp)² = (opp)² + (adj)². Plug the in:

(10)² = (7)² + (x)²

Evaluate

100 = 49 + x²

subtract 49 from both sides

100 - 49 = 49 - 49 + x²

51 = x²

square root both sides to get rid of the square

√51 = √x², the square cancels the square root

√51 = 7.14

7.14 = x

or x = 7.14 to the nearest tenth.

x = 7.1

                         Check

(10)² = (7)² + (7.14)²

100 = 49 + 50.97 ( approximately = 51)

100 = 49 + 51

100 = 100.

Hope this helps!

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
