Answer:
none of these is the correct .
THE CORRECT ANSWER IS = 54
Step-by-step explanation:
The sum of all angle of a triangle is 180 degree
So, Angle A + Angle B + Angle C = 180 degree
=78 + 48 + Angle C = 180
=126 + Angle C = 180
Angle C = 180 - 126
= 54 degree

Answer:
54
the sum of triangle measures is 180°
if angle A=78°,B=48°
therefore,angle C=180-A-B
C=180-78-48
=180-126
=54°
