Question

cosectheta+cottheta=3 then the value of costheta​

Answer 1

Step-by-step explanation:

cosθ + sinθ = 1

cosθ = 1 - 3/5 (sinθ = 3/5)

cosθ = 4/5

Answer 2

Answer:

The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°.
