Answer:

An obtuse triangle has all different measurements, which leaves your last two answers out.

If the angle at vertex B is obtuse, that means that the other two angles has got to be less than 90 degrees, because a triangle is 180 degrees, and your angles can't be more than 90 otherwise, you won't have a triangle.

Your answer is less than 90 degrees.

Hope this helps ;)

Arlecino [84]

Answer:

that would be the third one 12 ft, 12 ft, 20 ft because the lengths of 12+12 have enough to reach the 20 length compared to 30+30 which would only equal 60 and no more making it a line.

Can a system of two linear equations have exactly two solutions?
Elenna [48]
Most linear systems you will encounter will have exactly one solution. However, it is possible that there are no solutions, or infinitely many. (It is not possible that there are exactly two solutions.) The word unique in this context means there is a solution, and it's the only one.

Hope this helps.
