Concept:

Since it is mention in question that it is a five- sided polygon which means it has five sides and the angle sum property of a 5 sided polygon states that the sum of all angles will be 540^{0}.

Given:

Given ratio is 2:3:3:5:5.

Find:

We have find the measure of the smallest angle.

Solution:

Let the 5 angles be 2x, 3x, 3x, 5x and 5x respectively.

Using angle sum property:

2x + 3x + 3x + 5x + 5x = 540º

=> 18x = 540

=> x = 30

Now, the smallest angle is 2x = 2(30) = 60º

Hence, the final answer is (c) 60.
