Question

Acellus, Inscribed Angles
Find the value of y.
x
120°

Answer 1

`y=60\textdegree`

Explanation:

The Tangent-Secant Interior Angle Measure Theorem states that the measure of an angle formed by a tangent and a secant of a circle at the point of tangency is equal to half of the measure of its intercepted arc.

Therefore,
`y=(1)/(2) *120\textdegree = \bf 60\textdegree`. Hope this helps!
