Answer:
a= 53
b=53
c=127
d=48
e= 131
f=59
Step-by-step explanation:
a- a is supplementary to 127- so 180-127= 53
b- b is vertical to a- so- 53
c is vertical to 127, so it is 127
e is supplementary to 49. so 180=49= 131
The the sum of the interior angles of a quadrilateral is 360. to find d - subtract the values of 54, c, and e from 360 360-54-127-48= 48
f= sum of interior angles of a triangle is 180- 180-72-49=59
