The flag of a country contains an isosceles triangle. (recall that an isosceles triangle contains two angles with the same measure.) if the measure of the third angle of the triangle is 45° more than the measure of either of the other two angles, find the measure of each angle of the triangle.

The angles when added equal180
therefore:
x+x+(x+45)= 180
3x+45=180
3x=180-45
3x=135
x=135/3
x=45
therefor the angles
are 45, 45, 90 degrees

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
