3. In the diagram AC is a diameter of circle O. Points P and B are on the circle. a. Explain why k must be 2.
b. Find the coordinates of point O and the radius r of the circle.
c. Find the measure of minor arc AB. Give your answer accurate to at least one decimal place.

Thank you!

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

step-by-step explanation:

its 50 miles away from the starting point

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
