Answer:
The measurement of x is 56 degrees.
Step-by-step explanation:
Below that angle is a straight line measuring 180 degrees, so if one part of that 180 is 124 you would take 124 from 180.
180-124=x
x=56
Hope this has helped have a great day.
It looks like an equilateral triangle if I am correct then angle C equals 60 degrees
