Circle o is shown below. the diagram is not drawn to scale. what is the measure of angle bac?

134°
113°
56.5°
33.5°

angle BAC = 56.5 degree

Step-by-step explanation:

In the given circle O, AO  and BO are the radius of the circle

AO  and BO are same

So the angle opposite of AO and BO are also same

Angle BAC = angle ABO

WE know the sum of angles in a triangle is 180 degree

Angle BAC + ABO + O = 180 degree

Angle O = 67 degree

angle ABO = angle BAC

BAC + BAC + 67 = 180

2BAC + 67= 180

Subtract 67 on both sides

2BAC = 113

Divide by 2 on both sides

BAC = 56.5

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
