Answer:
39.3°, 140.7°
Explanation:
supplementary angles means that together they have 180°.
so, when we have 2 angles, x and y.
x + y = 180
x = y - 101.4
using the second equation in the first
y - 101.4 + y = 180
2y - 101.4 = 180
2y = 281.4
y = 281.4/2 = 140.7°
x = y - 101.4 = 140.7 - 101.4 = 39.3°
so, the starting angle is 39.3°, and every supplementary angle is then 140.7°.
