Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

The angles of a triangle are in the ratio $\var{num1*scale}:\var{num2*scale}:\var{num3*scale}$ .

Find the angles in degrees.

Gap 0. $^\circ$

Gap 1. $^\circ$

Gap 2. $^\circ$

Advice

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

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

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

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

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

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

Give a worked solution to the whole question.
