38. How many interior angles does the following 2-D shape hav 1) 5 2) 10 3) 8

To determine the number of interior angles in a polygon, you can use the formula: \[ \text{Number of interior angles} = n \] where \( n \) is the number of sides of the polygon. For the options you provided: 1) A shape with 5 sides (a pentagon) has 5 interior angles. 2) A shape with 10 sides (a decagon) has 10 interior angles. 3) A shape with 8 sides (an octagon) has 8 interior angles. So, the number of interior angles corresponds directly to the number of sides in each case. - For 5 sides: 5 interior angles - For 10 sides: 10 interior angles - For 8 sides: 8 interior angles If you are asking how many interior angles a specific shape has, please specify the number of sides of that shape.
