The angles of a triangle are in AdotPdot...

The angles of a triangle are in `AdotPdot` The number of degrees in the least is to the number of radians in the greatest as `60 :pidot` Find the angles in degrees.

Text Solution

Verified by Experts

Let the angles of the triangle be (a-d),a and (a+d).
Then ,
`(a-d)+a+(a+d)=180`
`=>3a=180`
`=>a=60`
Thus, the angle are `(60-d),60 and (60+d).`
So,Number of radians in the greatest angle.
`=>(60-d)/((60+d)×pi/(180))=(60)/pi`
