Question

Core stretch A ladder touches the edge $Y$ of a 5.5 m-high shed. The length $AY=6.5$ m and $BY=1.5$ m; find its angle with the ground. $5.5\text{ m}$ $AY=6.5\text{ m}$ $\theta$ $B$ $Y$ $1.5\text{ m}$ $A$ Give non-exact lengths and areas to 3 significant figures, and angles to 1 decimal place.

Accepted Answer

$\sin\theta=\dfrac{5.5}{6.5}$, so $\theta=57.8^\circ$.
