Question

HELP ASAP !!!!!!!!!! nnnnn

Answer 1

45.8

Explanation:

First solve for the other two sides by replacing x with 8

4(8)+7 = 39

3(8) = 24

Then use the pythagorean theorem (
`a^(2) + b^(2) = c^(2)`) to solve for the hypotenuse, c being the hypotenuse

`39^(2) + 24^(2) = c^(2)`

1521 + 576 =
`c^(2)`

2097 =
`c^(2)`

`√(2097) = \sqrt{c^(2) }`

45.8

Answer 2

45.8

Explanation:

We can use the Pythagorean theorem with legs 3x and 4x+7

a^2+ b^2 = c^2

(3x^2) +(4x+7)^2 = c^2

Let x = 8

(3*8)^2 + (4*8+7)^2 = c^2

24^2+ 39^2 = c^2

576+1521 = c^2

2097 = c^2

Take the square root of each side

sqrt(2097) = sqrt(c^2)

45.79301257 =c

Rounding to the nearest tenth

45.8 =c
