Question

Please solve question 30 on applications of AP ( Arithmetic Progression ) ​

Answer 1

Step-by-step explanation:

let the three angles in AP be x, x+a ,x+2a

then,

x +2a = 3(x)

x +2a = 3x

2x = 2a

x = a

so, x + x+a + x+2a = 180°

x + x + x + 3(x) = 180

3x + 3x = 180

x = 30

hence, the angles be 30 , 60, 90
