a cirlce has a diameter AB and an incribed at vertex C forming triangle ABC. The measure of angle A is 27 degreees. using what you know about inscribed angles, what is the measure of B? an incribed angle on a diamter will always measure 90 degrees forming a right trianlge with the corresponding diamter
whats the measure of B the answer is not 90 degrees
Since angle A is an inscribed angle that subtends the diameter AB of the circle, we know that angle B is an interior angle of the triangle and is supplementary to angle A. Therefore, angle B must be:
180 degrees - 27 degrees = 153 degrees
So, the measure of angle B is 153 degrees.
