Question

13. Given a circle with diameter BC and

inscribed angle BAC, make a conjecture
about the measure of this inscribed angle.
B

Answer 1

Explanation:

if BC is the diamater and angle BAC is inscribed, that means that BAC=90degrees, because the chord of the angle(BC) is equal to half a circle or 180 degrees and each inscribed angle is 1/2 of its respective chord. so angle B's value would be equal to 180-BAC-ACB=90-ACB(or angle C)
