Question

The minimum and maximum angles that can be drawn using two types of set squares are $x^{\circ }$ and $y^{\circ }$, then find $\frac{y^{\circ }}{6}-4x^{\circ }$.

Answer 1

The correct option is A 0.0
The minimum and maximum angles that can be drawn using two set squares are ${15}^{\circ }$ and ${360}^{\circ }$ respectively. As we have ${30}^{\circ },{45}^{\circ },{60}^{\circ },{90}^{\circ }$ from two set squares.

We can depict ${15}^{\circ }$ as ${45}^{\circ }-{30}^{\circ }$ and
${360}^{\circ }$ as ${90}^{\circ }+{90}^{\circ }+{90}^{\circ }+{90}^{\circ }$.

So,
$x^{\circ }={15}^{\circ }$, $y^{\circ }={360}^{\circ }$
$4x^{\circ }=4\times 15=60$
$\frac{y^{\circ }}{6}=\frac{360}{6}={60}^{\circ }\frac{y^{\circ }}{6}-4x^{\circ }=0$
