Question

In the given figure PQ parallel RS and
ACS=127° , BAC is
a)50°
b)53°
c)77°
d)107°​

Answer 1

Answer:

77 degree

Should be the right answer as angle ACS + angle CAQ =180 degree . therefore angle CAQ is equal to 53 degree. so angle p a q + angle bac + c a q equals to 180 degree.as they are linear pair and thus BAC is 77 degrees
