Sagot :
Answer:
b=80
c=80
Step-by-step explanation:
the angle opposite to the 100 degree angle is congruent to it
same goes for b and c
so far we have 2 angles that measure 100 degrees 100+100=200
the sum of the 4 angles is 360
360-200=160
160/2=80=b=c
they’re both 80 :)
because of where 100 is you can make a line where b and c are. a straight line is 180 so you subtract from 100 to get 80
