If m< 4 = (3x)o and m< 8 = (x+40)o what is the measure of < 4?

This problem needs more information. Probably a picture of a figure with several angles from which you can state the relationship between the angle 4 and the angle 8.

Then I have to assume this relation to show you how to work.

My assumptio will be that angle 4 and angle 8 are vertically opposite triangles.

That means that both triangles are congruent.

Then 3x = x + 40

=> 2x = 40
=> x = 20

Then agle 4 is 3x = 3*20 = 60 degrees.

60 degrees, subject to the assumption considered.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
