x = 21
Step-by-step explanation:
The angle T is an exterior angle to the ∆RST, so will be equal to the sum of the remote interior angles:
T = 4x° +2x° = 6x°
T is also a same-side exterior angle with the one marked 54°, so is supplementary to that:
T + 54° = 180°
6x° + 54° = 180°
x + 9 = 30 . . . . . . . . divide by 6
x = 21 . . . . . . . . . . . . subtract 9
Check
The triangle angles are ...
4x = 84°
2x = 42°
unmarked = 54°
Their sum is 84° +42° +54° = 180° . . . as it should be.

Simon is incorrect
Step-by-step explanation:
3^0 is not 0, it is 1.
A way of thinking about this is if to get from 3^2 to 3^1, you need to divide by 3, then to get from 3^1 to 3^0 you need to divide by 3 again. 3 divided by 3 is 1.
This means 3^0*3^2=1*9=9
