A) 18.3

Step-by-step explanation:

Since adding b and a gives 19.

c must be less than 19.

So, A) 18.3 is the correct answer

We know that the sum of measure of any two sides of a triangle is greater than the third Angle.

So, in this case,

Now, here only 19 is only greater than 18.3 from the options. Hence, 18.3 is the correct answer.

answer: the common difference is -0.10

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.
