Question

the angles of triangle in AP the great angle is twice the least angle of triangle, find the angle of triangle​

Answer 1

Step-by-step explanation:

let the least angle be x , the greatest angle became 2x

and let the third angle be y

these angles of triangle are in AP

i. e, x, y, 2x

so, y- x = 2x - y

2y = 3x

y = 3x/2 ....,i

now, x + y + 2x = 180°

3x + 3x/2 = 180°

9x/2 = 180°

x = 40°

then y = 3×40/2

y = 60°

so the angles of triangle are 40° ,60° , 80°
