What’s the answer?

Explanation:

PC = 12 is the radius, so 2*12 = 24 is the diameter

Circumference = pi*diameter = pi*24 = 24pi

Let x be the central angle APC.

To find the length of minor arc AC, we use this formula

L = (x/360)*(circumference)

L is the arc length and x is defined as above. Plug in 24pi for the circumference and plug in L = 68pi/15 which is the shortest distance from A to C along the circle. Solve for x

L = (x/360)*(circumference)

68pi/15 = (x/360)*(24pi)

68pi/15 = pi*x/15

68/15 = x/15 ... divide both sides by pi, the pi terms cancel

68 = x multiply both sides by 15, the denominators cancel

x = 68

The central angle APC is 68 degrees. Therefore, minor arc AC is 68 degrees as well.

Now use the inscribed angle theorem. This says that the inscribed angle is half that of the arc it cuts off. This means inscribed angle ABC is half that of minor arc AC.

angle ABC = (1/2)*(minor arc AC)

angle ABC = (1/2)*(68)

angle ABC = 34 degrees

step-by-step explanation:

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
