Answer:
B = 95°
C = 85°
Explanation:
the angle C is the opposite angle to that of 85 degrees, therefore congruent, we subtract 85 x 2 ° from the sum of the angles (360 °, is a round angle) and find the sum of the other two angles, always opposite and increasing, divide by two and we have the value of the angle B
C = 85°
B = [360 - (85 * 2)] : 2
B = (360 - 170) : 2
B = 190 : 2
B = 95°
-----------------
check
85 + 85 + 95 + 95 = 360°
the answer is good
