Due to short circuit, a fire has broken out in New Home Complex. Two buildings, namely $X$ and $Y$ have mainly been affected. The fire engine has arrived and it has been stationed at a point which is in between the two buildings. A ladder at point $O$ is fixed in front of the fire engine. The ladder inclined at an angle $60^{\circ}$ to the horizontal is leaning against the wall of the terrace $($top$)$ of the building $Y$. The foot of the ladder is kept fixed and after some time it is made to lean against the terrace $($top$)$ of the opposite building $X$ at an angle of $45^{\circ}$ with the ground. Both the buildings along with the foot of the ladder, fixed at $' O \ '$ are in a straight line.
Image
Based on the above given information, answer the following questions :
$(i)$ Find the length of the ladder.
$(ii)$ Find the distance of the building $Y$ from point $'O\ '$, i.e. $OA$.
$(iii)\ (a)$ Find the horizontal distance between the two buildings.
OR
$(b)$ Find the height of the building $X$.
