Bill is planning to construct a staircase. there is limited space, and the going of flight to be used is 3024mm. The floors are separated by 2184mmn(rise)
1) a suitable rise if one is approximately 170mm
2) the number of stair treads required
3)the going
4) the angle at which the staircase rises.
i have tried to answer but keep gettiung confused;
1) rise=2184/170
= 16.3
3) going= 3024/170
=17.78
4) tan=opp/adj
tan-1=2184/3024
=35.83
