64°/360° = 8/45 of the circle = 0.1777 (rounded, repeating)
The arc's length is 8/45 of the circle's total circumference.
Examples to show how to use the property that the measure of a central angle is equal to the measure of its intercepted arc to find the missing measures of arcs and angles in given figures.

102.8 degrees I think but it depends. If the angle is a central angle it is 51.4 degrees but other than that I think it would be 102.8 degrees.
In a circle, a central angle is formed by two radii. By definition, the measure of the intercepted arc is equal to the central angle.
A central angle is measured by its intercepted arc. Let's denote the length of the intercepted arc with s, and the length of the radius r. So, s = 6 cm and r = 30 cm. When a central angle intercepts an arc whose length measure equals the length measure of the radius of the circle, this central angle has a measure 1 radian. To find the angle in our problem we use the following relationship: measure of an angle in radians = (length of the intercepted arc)/(length of the radius) measure of our angle = s/r = 6/30 = 1/5 radians. Now, we need to convert this measure angle in radians to degrees. Since pi radians = 180 degrees, then 1 radians = 180/pi degrees, so: 1/5 radians = (1/5)(180/pi) degrees = 36/pi degrees, or approximate to 11.5 degrees.
The central angle of a circle is formed by two radii that extend from the center of the circle to its circumference. The intercepted arc is the part of the circle's circumference that lies between the two points where the radii intersect the circle. The measure of the central angle is equal to the measure of the intercepted arc in degrees. Thus, if the central angle measures θ degrees, the intercepted arc also measures θ degrees.
To find the measure of the intercepted arc for an inscribed angle, you can use the formula that states the measure of the intercepted arc is twice the measure of the inscribed angle. In this case, if the inscribed angle measures 67 degrees, you would calculate the intercepted arc as 2 × 67 degrees, which equals 134 degrees. Therefore, the intercepted arc would measure 134 degrees.

The measure of the intercepted arc is twice the measure of the tangent chord's angle. Therefore, if the measure of the tangent chord is 74 degrees, the measure of the intercepted arc would be 2 × 74 degrees, which equals 148 degrees.
It is the measure of half the intercepted arc.

The answer is half the measure, 62°. Have a nice day!
