Geometry ? circle o is shown below. what is the measure of bac?
(even if you just have the formula that would be )
a.53.5
b.146
c.36.5
d.107

A.

Step-by-step explanation:

We have been given an image of a circle. We are asked to find the measure of angle BAC.    

We can see that angle BAC and central angle BOC corresponds to same arc BC. By inscribed angle theorem measure of angle BAC would be half the measure of central angle BOC.

We can see that AC is diameter of circle as it passes through the center of our given circle. We will use linear pair of angles to find the measure of central angle BOC as:

Since BAC is inscribed angle, so its measure would be half the measure of central angle BOC.

Therefore, the measure of angle BAC is 53.5 degrees and option A is the correct choice.

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12

the answer will be b x² +x-1
