I don't the answer please help me

To construct a triangle ABC with the given side lengths AB = 70mm, BC = 90mm, and AC = 120mm, we can use the fact that the sum of any two sides of a triangle must be greater than the third side.

Here are the steps to construct the triangle:

1. Draw a line segment using a ruler and label it AB with a length of 70mm.
2. From point A, use a compass to draw an arc with a radius of 90mm. This arc will intersect the line segment AB at two points. Label the point of intersection as C.
3. From point B, use a compass to draw an arc with a radius of 120mm. This arc will intersect with the previous arc drawn in step 2 at two points. Label the point of intersection as C.
4. Using a ruler, draw a line segment between points C and B.
5. Label the intersection point of AB and BC as point C.

Now you have successfully constructed triangle ABC with side lengths AB = 70mm, BC = 90mm, and AC = 120mm.
