Answer:
36.1\ units^2

Explanation:

You need to use the SAS area formula. This is:


A=(a*b*sin(\alpha))/(2)

Given the triangle ABC, you know that:


a=AC=10\ units\\b=BC=17\ units\\\alpha=\angle ABC=25.1\°

Therefore, substituting these values into the formula, you get that the area of the triangle ABC is:


A=((10\ units)(17\ units)*sin(25.1\°))/(2)\\\\A=36.1\ units^2
