90 - 47 = 43

x = 43
vertical angles are equal

hope it helps

We know that angles on a straight line sum to 180°, and we can see that 90° has already been defined on the left top left hand, leaving us with 90° on the top right hand. We are given 47°, so that must mean that the angle between the right angle and the 47° angle is:
90-47= 43°
Opposite angles around a 360° point are equal, and we see that angle x is opposite the 43° that we just found out. Therefore, x= 43°
