Question

there is angles. angle 2 = 47 but we need to figure out what angle 4 equals. 2 and 4 are not vertical to each other but 4 and 1 are. 3 and 5 are not vertical either
GPT 3.5
In order to find the value of angle 4, we need to use the vertical angles theorem. According to this theorem, vertical angles are equal in measure. Since angle 4 and angle 1 are vertical angles, we can conclude that angle 4 is also equal to 47 degrees.
