Question

The angle of a triangle are in AP the greatest to them being 80 degree find all the three angles in a triangle?

Answer 1

Step-by-step explanation:

let the angles be a-d,a,a+d. a-d+a+a+d= 180(ASP)3a =180 a=60 given that a+d = 80 so, a+d - a = 80- 60 d = 20 so , angles are a-d = 40a = 60 a+ d =80 1 degree = 0.0175 radians so, 40d = 0.7 radians 60d = 1.05 radians 80d = 1.4 radians
