An intercepted arc has a length of 19 yards. If the radius is 4 yards, find the measure of the central angle in radians and degrees.

The length of an arc is the distance between the endpoints of the arc.

The central angle is: or

The given parameters are:

--- length of the arc

-- radius of the circle

The length of an arc is calculated as:

Divide both sides by r

Substitute known values

Convert to degrees as follows:

Hence, the central angle is: or

19*4=76

Step-by-step explanation:

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

the height of the surface increases from the center out to the sides of the road

it is c!
