Question

Solve for x. Round to the nearest tenth.​

Answer 1

Using the pythagorean theorem, we have :


`x^(2) = 19^(2) + 16^(2)`


`x^(2) = 617`


`x = √(617) = 24.8394846967...` (round to 24.8)

Answer 2

24.8

Explanation:

This is pythagorean theorem since it is a right-angled triangle.

A^2 + B^2 = C^2

Where A and B is the 2 sides that make the right angle

And C is the hypotenuse (the longest side)

So we just substitute in

19^2 + 16^2 = C^2

361 + 256 = C^2

617 = C^2

sqrt(617) = C

24.839 = C

Rounded up to the nearest tenth = 24.8
