If you multiply 2x2 you get 4 and multiply another 2 which is 8. Two answers are 8 and 2x2x2.
Radius is half of the diameter so it's 7 for the diameter.
Additive Identity Property is the answer.
First you would need to solve x.
2x+x+14+x-38=180
4x-24=180
4x=204
x=51
Now plug in the x for all three angle measures.
2(51)=102 degrees
51+14=65 degrees
51-38=13 degrees
Final answer is 102 degrees, 65 degrees, 13 degrees
