Step-by-step explanation:
4) The sum of the triangle is:
P= 49 in
To find X:
[tex]49 - (18 + 12)[/tex]
we will add the two sides given and then minus it with the total.
[tex]49 - 30 = 19[/tex]
so, x is:
[tex]19 \: in[/tex]
Classify the triangle by its side measures:
Scalene triangle. This is because the sides of the triangle are of different lengths. Additionaly, all the sides are different numbers.
