Answer:
Step-by-step explanation:
You need to use the SAS area formula. This is:
Given the triangle ABC, you know that:
Therefore, substituting these values into the formula, you get that the area of the triangle ABC is:
x = 10
3x - 5 = 2x + 5
3x - 5 + 5 = 2x + 5 + 5
3x = 2x + 10
3x - 2x = 2x - 2x + 10
1x = 10
