1.	An internal angle of an equilateral surface is132Â° more than its exterior angle. Find thenumber of sides in the equilateral surface.
Answer» The answer is 15 Let exterior angle be x Then, Interior angle = x+132 Now, Interior angle +Exterior angle = 180 or, x + x + 132 = 180 or, 2x = 48 or, x = 24 So, number of angles = 360/exterior angle = 360/24 = 15 Correct Ans of this question = 15

An internal angle of an equilateral surface is132Â° more than its exterior angle. Find thenumber of sides in the equilateral surface.

Answer»

The answer is 15

Let exterior angle be x

Then, Interior angle = x+132

Now, Interior angle +Exterior angle = 180

or, x + x + 132 = 180

or, 2x = 48

or, x = 24

So, number of angles = 360/exterior angle = 360/24 = 15

Correct Ans of this question = 15
