Angles XYO and XTY are inscribed in one circle. Find the degree measure of the angle XYO

Angles XYO and XTY are inscribed in one circle. Find the degree measure of the angle XYO, if XTY = 70 degrees, and points O and T lie on the same side of the line XY.

In Figure 2, the inscribed angle ХТУ is equal to 70 and rests on the arc ХУ. The inscribed angle ХОУ also rests on the XY arc, then the angle ХОY = ХТУ = 70 = 70.
Answer: Angle XOY is 70.
