Question

. The angles of a triangle are in A.P., the greatest of them being 80º; find all the three angles in radians.
​

Answer 1

Step-by-step explanation:

let the angles be a-d, a, a+d

we know that,

a-d+a+a+d=180

3a=180

a=60

then

a+d=80

d=20

angles are 40,60 and 80

the angles are (40*60) (60*60) (80*60)

(2400,3600,and 4800)
