The length of a cell phone is 2.2 inches and the width is 4.6 inches. The company making the cell phone wants to make a new version whose length will be 2.09 inches.
Assuming the side lengths in the new phone are proportional to the old phone, what
will be the width of the new phone?

The width of the new phone will be of 4.37 inches.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

In this question:

Length was of 2.2 inches, after the modification is of 2.09 inches.

Width was of 4.6 inches, after the modification is x. So

2.2 - 2.09

4.6 - x

Applying cross multiplication:

The width of the new phone will be of 4.37 inches.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
