X/sin 42 = 43/sin 87
x = (43 * sin 42)/(sin 87)
x = 28.812

Answer: 60 degrees
Step-by-step explanation:
Since we know that the sum of the angles in a triangle is 180 degrees, that means x + x+ x = 180.
3x = 180
x = 60.
Another way we could figure out that x = 60 was by realizing that this is an equilateral triangle, which means each angle must = 60 degrees.
