The angles of a triangle are in AP. The greatest angle is twice the least Find all the angles About the author Anna
Step-by-step explanation: Correct option is A 40,60,80 Let the angles be a−d,a,a+d. & 2(a−d)=a+d,2a−2d=a+d,a=3d⟶(i) a−d+a+a+d=180°,3a=180°,a=60°.d=20°. a−d,a,a+d=40,60,80 Reply
Step-by-step explanation:
Correct option is
A
40,60,80
Let the angles be a−d,a,a+d.
& 2(a−d)=a+d,2a−2d=a+d,a=3d⟶(i)
a−d+a+a+d=180°,3a=180°,a=60°.d=20°.
a−d,a,a+d=40,60,80
