Answer: 56 degrees please read explanation so you understand
Step-by-step explanation:
The triangle is equilateral so all the interior angles are the same that means if you find value of one of the angles you will get all of them.
Its hard to explain without a pic but one side of the triangle is straight and a straight line has an angle measure of 180 degrees so if you do 180-124 you will get your answer. I hope this helped you.
