Answer(s): Reading your answers from top left, top right, bottom left, bottom right;
Circle A: 110, 70, 70, 110
Circle B: 127, 53, 53, 127
Step-by-step explanation:
Each circle will add up to 360 degrees.
Both acute and obtuse angles are congruent (the same or identical).
If you have an acute angle of 70 for circle 'A', your other acute angle is 70 as well since they are congruent.
Your other two angles will have to equal 220 because you already have 140 degrees and your circle needs to equal 360 degrees. Both of your unknown angles are identical, so divide 220 by 2 to get 110 for both your obtuse angles.
Do the same for your second circle.
Multiply 53 by two to get 106, then subtract 360 by 106 to get 254.
Divide 254 by 2 to get 127 for both of your obtuse angles.
