Question

What is the base of the triangle? (:

Answer 1

The base of the triangle ABC is 12 units.

Step-by-step explanation:

Step 1; First we need to identify which side is the base of the triangle. In this given triangle side CB is the base. So we plot points C and B on the graph. Coordinates for C are (-4, -3) and for B are (8, -3). We need to find the distance between the 2 edges of the triangle.

Step 2; To find the distance of CB, we use the formula;

Distance = √ (x2 - x1)² + (y2 - y1)².

Distance between C (-4, -3) and B (8, -3) where C is (x1, y1) and B is (x2, y2).

Distance = √(8 - (-4))² + (-3 -(-3))² = √12² + 0² = √12² = 12 units.

Similarly, triangle ABC's height equals 10 units.
