Answer: -110° and -470°
Step-by-step explanation:
Co-terminal angles are those angles who share the same initial side and terminal sides.
These angles are obtained by adding or subtraction 360° in the angle.
That is, If Ф is an angles,
Then its co-terminal angle is,
Ф + 360° n
Where n is an integer.( Negative or positive )
Here, Ф = 250°
Thus, For finding the first two angles with negative measure,
We must put n = -1 and n = -2 in the above equation.
Hence, the required angles are,
(250° + 360° × - 1 ) and (250° + 360°×-2)
= (250° - 360°) and (250°-720°)
= -110° and -470°
