Answer:

14.5 degrees

Step-by-step explanation:

The total amount of degrees in a triangle is 180

67.5+55=122.5 degrees

That means that there would be 57.5 (180-122.5) degrees left for the measure of angle 3x+14.

3x+14=57.5

-14     -14

3x=43.5

x=14.5

Answer:

Since this is an equilateral triangle, the two angles at he bottom are equal. 55-14= 41, and 41/3= 13 2/3, so x=13.6 repeating.
