Question

The angles of a triangle are in ap the greatest angle is twice the least fine the angles

Answer 1

Answer:

hey!!

Step-by-step explanation:

Question

The angles of a triangle are in ap the greatest angle is twice the least fine the angles

ans .

given : angles are in ap

ATQ,

smallest angle = a - d

2nd angle = a

bigger angle = a +d

by angle sum property,

a-d +a+a+d= 180°

3a = 180°

a = 60°

also given that

greatest angle is twice the least

2(a-d) = a+d

2(60 -d) = 60 +d

120 -2d = 60 + d

60 = 3d

d = 20

hence the diff of the angles if 20°

hence the angles are 40,°60° and 80°

Answer 2

Answer:

Answer

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.
