Short leg= long leg / √3
x + my height ( up to my eyes) = the height of the goal post
23.09+5=height of goal post
In a 45-45-90 Δ, leg=leg, so x=22 ft.
My height to my eyes≈5.58 ft
Height of the Goalpost≈27.58 ft
22 ft+5.58 ft=27.58 ft
x+my height ( up to my eyes)=the height of the goal post
24.25+4.8=height of goal post
Short leg=Long leg√3
20.52+5.25=height of goal post
We learned how to use geometry, trigonometry, and special right Δs in everyday life to solve for height and length based problems that can be used in architecture and design. Our average goal post height was 27.62.
