Answer:

a) is not a triangle.

b)

Okay, so I used this method to determine if the measurements will make a triangle.

a+b has to be greater than c. 7+2= 9. So 9 is greater than c

a+c has to be greater than b.  7+ 5= 12. which is greater than b

c+b has to be greater than a. 5+ 2 is 7. which is equal to a.

That means it would not make a triangle. Because c+b must be GREATER than a.

Consider doing the 2nd one the way I did the first question.

You got this!!
