Respuesta :
The vertical height of the tank is 7 inches and the length of the ramp = 15.7 inches
What is Pythagoras theorem?
The Pythagoras theorem states that in a right-angled triangle, the square of the longest side is equal to the sum of the squares of the other two sides.
The vertical height of the tank is 7 inches.
The horizontal distance spanned by the ramp = 14 inches.
This all forms a right-angled triangle with the length of the ramp as the hypotenuse.
By Pythagoras theorem,
(Hyp)² = (Opp)² + (Adj)²
(Hyp)² = 7² + 14²
(Hyp)² = 245
Hyp = 15.65 inches = 15.7 to 1 d.p.
Hence, the length of the ramp = 15.7 inches
