Answer:
158 degrees
Step-by-step explanation:
Here, we want to find the sum of the two angles.
If A is a supplement of B, it means that adding A and B together will yield 180 degrees
Mathematically;
A + B = 180
A + 124 = 180
A = 180-124
A = 56
Also, A is a complement of C
This means that adding A to C yields 90
A + C = 90
C = 90- A = 90 -56 = 34
Thus B + C = 34 + 124 = 158
