Regina draws a triangle inside a circle; she labels the vertices ABC, with the diameter as AB and the inscribed angle as C. She draws the length of AB 14 cm long, and AC 8 cm long. Using what you know about inscribed angles, what will be the approximate angle measure of B?(1 point) Responses 90° 90° 55° 55° 70° 70° 35°
By the properties of inscribed angles, the angle at the center of the circle is twice the measure of the inscribed angle. Since the inscribed angle C is half the angle at the center of the circle, we can set up the equation:
Angle at center = 2 * C
Angle at center = 2 * 35° = 70°
Therefore, the approximate angle measure of B is 70°.
