Answer:

so required angles are 50.7°and 129.3°

Step-by-step explanation:

Let the angle be x

another angle = x + 78.6°

so,

x + x + 78.6° = 180° {being sum of supplementary angle}

so, 2x + 78.6° = 180°

or, 2x = 180° - 78.6°

or, x = 101.4/2

so, x = 50.7°

so another angle = x + 78.6°

= 50.7° + 78.6°

= 129.3°
