Line segment ts is tangent to circle o at point n. if the measure of angle qnt is 74 degrees, what is the measure of arc qpn?

I'm pretty sure it is 148° in my notes it says "if a tangent to a circle & a chord intersect at a point on the circle, then the measure of each angle they form is one-half the measure of its intercepted arc." hope this

The answer is 148 degrees
