The intersection angle of a 3 degree curve is 45.2 degrees. what is the length of the curve? of select one: o a. 455 m o b.573 m c. 452 m o d. 25.9 km

Explanation:

Relation between length of a curve and angle is as follows.

               l =

where,   R = radius of curve

          = angle in radians

Also,     l =  .......... (1)

If curve has a degree of curvature for standard length s, then

               R =   ........... (2)

Now, substitute the value of R from equation (2) into equation (1) as follows.

               l =  

If s = 30 m, then calculate the value of l as follows.

                 l =  

                   =              

                   = 452 m

thus, we can conclude that the length of the curve is 452 m.

they are made of gases.

they have a spherical shape.

they make energy through fusion.
