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°
66 rounded to the nearest hundred is 100.
If the last two digit of the number are 50 or above round up.
But....
If the last two digit of the number are 49 or below round down.
But remember also.....
If the last two digit are zeros, do not round, it is already in the hundred.
Hope this helps u.
