Answer:
Step-by-step explanation:
2 radians = 360 degrees
the difference of two angles = 20 degrees
a - b = 20 --------------------> 1
the sum of two angles = 360 degrees
a + b = 360 -------------------> 2
equation 1 + 2
2 a = 380
a = 190
substitute in equation 2
190 + b = 360
b = 360 - 190
b = 170
Solution (a=190, b=170)
