Question

The minimum angle that can be drawn using two types of set squares is $x^{\circ }$, then find $\frac{x}{3}$.

• A. 5

Answer 1

The correct option is A 5
The minimum angle that can be drawn using two set squares is ${15}^{\circ }$. As we have ${30}^{\circ },{45}^{\circ },{60}^{\circ },{90}^{\circ }$ from two set squares.

We can draw ${15}^{\circ }$ as ${45}^{\circ }-{30}^{\circ }$.


Therefore, $x^{\circ }={15}^{\circ }$
$\therefore \frac{x}{3}=5^{\circ }$
