"In order to meet ADA requirements, a wheelchair ramp must have an angle of elevation of no more than" the angle of elevation is mathematically given as

∅=3.434

What angle of elevation will this ramp have?

Generally, the equation for the angle is mathematically given as

[tex]\theta=\frac{opp}{adj}\\\\Therefore\\\\tan\theta=\frac{1.5}{25}\\\\tan\theta=\frac{1.5}{25}\\\\\theta=tan^{-1}\frac{1.5}{25}\\\\[/tex]

∅=3.434

In conclusion, the angle of elevation

∅=3.434
