Question

If the angles in a triangle are AP then what is the condition

Answer 1

Answer:

One of the angle of triangle is 60 degrees

Step-by-step explanation:

Let the angles of a triangle be

A-d, A and A+d

since the sum of the angles of triangle is 180 degrees, we have

(A-d)+A+(A+d)=180

3A=180

A=180/3

A=60 degrees.
