- Solve for x.
Okay, so from the given figure we can see that, < FAE & < FAB forms a linear pair. In a linear pair, the 2 angles will together sum up to 180°. So,
- < FAE = 4x°
- < FAB = 2x°

From the explanation, we can understand that,
Sum of the linear pair = 180°
< FAE + < FAB = 180°
4x° + 2x° = 180°
6x° = 180°
x° = 180 ÷ 6
x = <u>3</u><u>0</u><u>°</u><u>.</u>

- The value of x will be<em><u> 30°</u></em> (3rd option).
