In the figure, yx is a tangent to circle o at point x.
measure of xb = 52 degrees
measure of xa = 104 degrees
what is the measure of xya?

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
