a commonly accepted angle of elevation for a safe, accessible wheelchair ramp is 4.4 degrees. The public library's main door is 0.9 m above street level. what will be the run of this ramp

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
