Did you figure it out?

Solution:  Since the sum of the measures of all 5 vertices of a pentagon is 540°, that means that each angle is 540° ÷ 5 = 108°. Two 108° angles and x make a full 360° circle, so 360° – 108° × 2 = 360° – 216° = 144°. So, the measure of x is 144°.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Did you figure it out?

Solution:  The length of the box is equal to 11 erasers, the width is equal to 9 erasers, and the depth is equal to 7 erasers. So, the box will hold 11 × 9 × 7 = 693 erasers in total.
