The areas of two similar triangles are 20m2 and 180m2. the length of one of the sides of the second triangle is 12m. what is the corresponding side of the first triangle?

4 meters.

Step-by-step explanation:

1. First, let's calculate the ratio of the sides of the triangles as following:

2. You know that the length of one of the sides of the second triangle is 12 meters, therefore, you must multiply the ratio calculated by that side, as following:

3. Therefore,  the lenght of the corresponding side of the first triangle is 4 meters.

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
