Answer 1

Answer:

170 deg and 190 deg

Step-by-step explanation:

The difference of angles: a-b=20

Sum of angles: a+b=2 rad=360

From the first equation: a=b+20

Considering this in Second equation we get: a+b=360

b+20+b=360

2b=340

b=170

We can find a now: a=b+20=170+20=190

So the answer is 170 deg and 190 deg
