Question

the angles of triangle are in the AP .if one angle is 55 .find the other angles of triangle​

Answer 1

Step-by-step explanation:

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

a-d + a+d + a= 180°

3a=180°

a= 180°/3

a= 60°

Hence the two angles would be : 55° and 60°

50°+60°+3rd angle = 180°

110°+3rd angle= 180°

3rd angle= 180°-110°

3rd angle= 70°

Therefore, angels of the given triangle will be 70°,60°,50° or 50°,60°,70°

Answer 2

Hope this helps just used the AP formula and the fact that a triangle is equal to 180
