Answer 1

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

So, in this case,

• ( a + b ) > c

• Or, 9 + 10 > c

• Or, 19 > c

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

Answer 2

A) 18.3

Explanation:

Since adding b and a gives 19.

c must be less than 19.

So, A) 18.3 is the correct answer
