\n

Add the three ratios together, which gives $\\var{15*scale}$

\n

Therefore 1 part is equal to $\\frac{180}{\\var{15*scale}}=\\var{12/scale}^\\circ$

\n

Multiply each element in the ratio by $\\var{12/scale}$ to find the value of each angle in degrees

\n

$\\var{12/scale} \\times \\var{num1*scale}=\\var{12*num1}^\\circ$

\n

$\\var{12/scale} \\times \\var{num2*scale}=\\var{12*num2}^\\circ$

\n

$\\var{12/scale} \\times \\var{num3*scale}=\\var{12*num3}^\\circ$
