The measure of ______________ in a circle is half the measure of the intercepted arc.
2 answers:
Answer: C. An inscribed angle
Step-by-step explanation:
Central angle is an angle that is subtended by an arc in a circle, it is also known as the arc's angular distance.
Interior angle is an angle between two sides inside a polygon or a shape.
Inscribed angle is an angle formed by two chords in a circle which have a common endpoint, and by the inscribed angle theorem, the measurement of inscribed angle is half the measure of the intercepted arc.

Answer:
vertex = (- 1, 1 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = -
y = x² + 2x + 2 ← is in standard form
with a = 1 and b = 2 , then
x = - = - 1
substitute x = - 1 into the equation for y- coordinate of vertex
y = (- 1)² + 2(- 1) + 2 = 1 - 2 + 2 = 1
vertex = (- 1, 1 )
