Question

Find the value of F

Answer 1

f = 25.85751233

Explanation:

f^2+E^2=26^2

Answer 2

f = 13
`√(2)`

Explanation:

Given that f and e are congruent then e = f

Using Pythagoras' identity in the right triangle

f² + e² = 26² , that is

f² + f² = 676

2f² = 676 ( divide both sides by 2 )

f² = 338 ( take the square root of both sides )

f =
`√(338)` =
`√(169(2))` = 13
`√(2)` ≈ 18.4 ( to 1 dec. place )
