Question

I’m kind of having troublehelp?

Answer 1

c = 13.0

Explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

c² = 11² + 7² = 121 + 49 = 170 ( take the square root of both sides )

c =
`√(170)` ≈ 13.0 ( to the nearest tenth )

Answer 2

13

Explanation:

a^2 + b^2 = c^2

11^2 + 7 ^2 = c^2

121 + 49 = 170

√170 = 13.04
