Gap-fill

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

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

Find the angles in degrees.

Gap 0.degrees

Gap 1.degrees

Gap 2.degrees

Advice

Part 1:

Add the three ratios together, which gives $15$

Therefore $1$ is equal to $\frac{180}{15}$ degrees (12degrees)

Multiply each ratio by 18 to find the value of each angle in degrees

$12 \times \var{num1}$

$12 \times \var{num2}$

$12 \times \var{num3}$

Part 2:

Add the three ratios together, which gives $10$

Therefore $1$ is equal to $\frac{180}{10}$ degrees (18degrees)

Multiply each ratio by 18 to find the value of each angle in degrees

$18 \times \var{numberthree}\frac{1}{\var{numberthreea}}$

$18 \times \var{numberfour}\frac{1}{\var{numberfoura}}$

$18 \times \var{numberfive}\frac{\var{numberfiveb}}{\var{numberfivea}}$
