Question

A triangle has a total of 180 degrees, If the ratios are 3:7:2, then you want to make sure about how much each side will measure. For example, if you have a side of 3, then to find the angle measure you need to see how many times three goes to 190. To find that out you need to do 3x=180 and see how much x equals to. Try that out for each of them and make sure that the angle measures add up to 180 degrees.
