Question

Core stretch Points $B,C,D$ are collinear. Given $AC=10$ cm, $AD=10\sqrt2$ cm, $\angle ACB=\angle ACD=90^\circ$, and $\angle ABC=30^\circ$, calculate $AC=10$ $AD=10\sqrt2$ $B$ $C$ $D$ $A$ $X$ $30^\circ$ Give non-exact lengths and areas to 3 significant figures, and angles to 1 decimal place.

Accepted Answer

(a) $20$ cm (b) $45^\circ$ (c) $25\text{ cm}^2$.
