Answer
We draw $AB=5\hspace{2mm}cm$ using a ruler. Placing the protractor at $A$, we draw a $17^o$ angle with a dotted line. Placing the protractor at $B$, we draw a right angle again with a dotted line. The two dotted lines intersect at $C$. We see triangle $ABC$ is a right-angled triangle, from where we can approximate $sin17^o$ and $cos17^o$.
