If the angles of A, B and C of a ΔABC are in A.P. and the sides a, b and c opposite to these angles are in G.P., then a2, b2 and c2 are in –
Question
Solution 1
The given conditions are that the angles A, B, and C of a triangle ABC are in Arithmetic Progression (A.P.) and the sides a, b, and c opposite to these angles are in Geometric Progression (G.P.).
From the given conditions, we can write:
B = A + d and C = A + 2d (since the angles are in A.P.)
