Question

By law, a wheelchair service ramp may be inclinedno more than 4.76º. If the base of a ramp begins 15feet from the base of a public building, whichequation could be used to determine the maximumheight, h, of the ramp where it reaches thebuilding's entrance?h1) sin 4.76° =15152) sin 4.76°hh3) tan 4.76° =15154) tan4.76° =hChoose

Answer 1

We have the next diagram in order to understand better the question

We this in mind we can use a trigonometric function in this case the tangent because it is the one that relates the two sides given

$\tan (\theta)=\frac{co}{ca}$$\tan (4.76)=\frac{h}{15}$
