to find length of the pole x use the Pythagoras theorem 29^2 = x^2 + 21^2

i thought that but wasnt sure @welshfella
welshfella
  • welshfella
yes that's the way x^2 = 29^2 - 21^2 x = sqrt (29^2 - 21^2)

having found the value of x you use pythagoras again on the other triangle

y = √(20^2 + 30^2) = 10√13 ≈ 36.1 ft
