You can put this solution on YOUR website!
angle A+=+x-10
angle C is x=2 and
angle B+=+2x
first solve for x which
x-10%2B2x%2Bx%2B2=180+...here I see that angle C=x%2B2 not x=2
4x-8=180+
4x=180%2B8+
4x=188+
x=188%2F4+
x=47+
then angle B is 2x=2%2A47=94 degrees

check:
A+=+x-10=47-10=37
B+=+94
C=x%2B2=47%2B2=49
37%2B94%2B49=180
180=180
