I don't see a figure, so I'll mention two possibilities. There are more possibilities. Since the arc is named arc AC, points A and C must be on the circle. Since I don't see the figure, I don;t know where point B is.

If point B is on the circle, then angle ABC is an inscribed angle. The measure of an inscribed angle is half the measure of the intercepted arc, so m<ABC = 156/2 = 78.

If point B is the center of the circle, then angle ABC is a central angle. The measure of a central angle is the same as the measure of the intercepted arc, so m<ABC = 156.

Do you have one of the two situations above?

Answer:

135 degrees

Step-by-step explanation:

all the angles in a triangle need to add to 180 degrees, so you take

180-(65+70)= 45

Then you just find the supplementary angle

45+x=180

x=135

Answer:  $15.00 per person.
______________________________
Explanation:
______________________________
 Given that there are "4 people" (that is, "Kianna and three friends");
____________________________________________________
and a total of "$58.49" ; to be divided equally among 4 (four) people;
______________________________
 we are asked to <em><u>estimate</u></em> the amount that EACH person will pay.
______________________________
For an <em><u>ESTIMATE</u></em>,  $58.49 is ABOUT $60.00; or "60 dollars". ;

and (60 dollars) / 4 = 15 dollars {$15; or $15.00}. 

60/4 = 15;  or 60/4 = (60÷2)/(4÷2) = 30/2 = 15.
