Answer:

Firstly, identify all the pairs of vertically opposite angles. Vertically opposite angles are equal.

In this case,

AOC & DOB are vertically opposite angles so both of them are 2x°

EOD & COF are vertically opposite angles so they are both 3x°.

FOB & EOA are vertically opposite angles so they are both x°.

Adding the values of all 6 angles, we get:

3x + 3x + 2x + 2x + x + x = 12x

We also know that

12x = 360°

x = 30°

Step-by-step explanation:

P = 2(l + w)

P = 2(3a + 3 + 8a - 12)

P = 2(11a - 9)

P = 22a - 18

P = 22(3) - 18

P = 66 - 18

P = 48

P = a + b + c

P = 3b + 7 + 7b - 2 + 7b - 2

P = 17b + 3

P = 17(6) + 3

P = 102 + 3

P = 105
