Diagram not drawn to scale
Calculate the size of each of the angles \(f\) and \(g\). [3]
\(f\) = ……………… ° \(g\) = ……………… °
| Scheme | Marks | Comments |
|---|---|---|
| f = 73(°) | B1 | |
| g = 128 – 73 | M1 | F.T. 128 − ‘their f’. |
| = 55(°) | A1 |
Alternative method
| Scheme | Marks | Comments |
|---|---|---|
| f = 73(°) | B1 | |
| g = 180 – (180 −128) – 73 | M1 | FT ‘their f’. |
| = 55(°) | A1 |
