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,

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).

Answer:
She will cycle 85.169 miles in the third week.
(round if needed)
Step-by-step explanation:
56÷100=0.56 (this is 1%)
0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)
repeat for the other 3 weeks
64.4÷100=0.644
0.644 x 15 + 64.4 = 74.06
74.06÷100=0.7406
0.7406 x 15 + 74.06 = 85.169
Answer: Rs 280
A dozen = 12
12 notebooks --> Rs 480
1 notebooks --> 480/12 =Rs 40
7 notebooks --> 40 * 7 = Rs 280
