You apply the sum of interior angles formula ie. (n-2)180. n=number of sides
since a pentagon has 5 sides it will be (5-2)180=540.
now add everything. x-5+x-6+2x-7+x+2x-2=540.
Solve for x: 7x-20=540
7x=540+20
7x=560
x=560/7
x=80

Answer:
18 cm
Step-by-step explanation:
The ratio of Actual length (L) to scale length is 27 : 3.6
27 ÷ 3.6 = 7.5
Therefore, actual width (W) = scale width x 7.5
= 2.4 x 7.5
= 18 cm
