Answer:

x = 61

Step-by-step explanation:

Formula:

(N {which is the number of sides in the polygon] - 2) * 180 = the sum of all the angles in the polygon.

Simply add the known angles together, subtract that from the above equation and you get the value of x.

(5 {which is N] - 2) * 180

3 * 180 = 540

82 + 121 + 129 + 147 = 479

540 - 479 = x

540 - 479 - 61

x = 61

b = 24 cm

h = 10 cm

S1 = 26 cm

S2 = 24 cm

S3 = 10 cm

L = 34 cm
