Need to find x then all the degrees in each in angle.

Both of these angles are vertical meaning that they are congruent so you have to set them equal
6x=4x + 16
Then subtract 4x from both sides to get:
2x=16
Then divide by two on each side to get
X= 8
To find the measure of the angles multiply the value of x which is 8 with 6 (8x6) to get 48 for both angles!
