as all angles are in ap so let assuma it to be a-d ,a,a+d so total is
3a =180° a= 60°
the biggest angle is 84
the smallest angle is 36
the angle in radians are π/10`;
π/3` and 7π/15`
voldemort07:
btw i guess its 2Π/10 instead of just Π/10 which is just 18°

Given:
The angles of a triangle are in AP. The greatest angle is 84°.
To find:
All the angles in radian.
Solution:
The angles in radian, if the angles of a triangle are in AP, and the greatest angle is 84°, are
We can solve the above mathematical problem using the following mathematical approach.
As the angles of the triangle are in Arithmetic progression, let the angles be a-2d, a-d, and a.
According to the question, the greatest angle is 84°.
⇒ a = 84°
The sum of all the angles in a triangle is 180°. So,
Angles in radian =
Therefore, the angles are
