Answer 1

You can use Pythagorean theorm to solve.


`a^2 + b^2 = c^2`
C = 3959 + 2.9 = 3961.9

x = ???? = a
b = 3959
Plugin our data.

`a^2 + b^2 = c^2`

`a^2 + 3959^2 = 3961.9^2`

`a^2 + 15673681 = 15696651.61`

`a^2 = 22970.61`

`√(a^2) = sqrt{22970.61}`

`a = 151.560`

`x = 151.560`

`x = 151.6`
