Respuesta :

as a fraction of 180, m < 1 = 1/ (1 + 3 + 2) * 180 = 1/6  * 180  = 30 degrees

m < 2 = 3*30 = 90 degrees

and m < 3 = 30*2 = 60 degrees

We know that a straight line is 180 degrees. I'm not sure how to really explain, so bear with me:

We know that 3 in the ratio is 3x 1 in the ratio.

180 divide 3 (parts) = 60

So 3 in the ratio has to be more than 60.

I tried 90.

30 + 90 + 60 = 180

This is the right answer 1/3 of 90 is 30 (1:)

90 is 3/3 (3:)

2/3 of 90 is 60 (3:)

Not really detaild but hopes this helps!
