Will give brainlist im so confused

Step-by-step explanation:

1) Find the measurement of the angle of the arc:

let x = the missing angle

360 = 73 + 65 + 150 + x

x = 72

2) Find the circumference

r = 6.48

C = 2(6.48)(3.14)

C = 40.6944

3) Multiply the circumference by the angle measurement divided by the the angle measurement of the circle:

40.6944 * (72/360)

= 40.6944 * (1/5)

=8.13888

4) Round to the nearest tenth
