Question

if the measures of the angle of a triangle are in arthimetic progression .if the greatst is thrice times the least then the least is​

Answer 1

Answer:

30

Step-by-step explanation:

since it is a triangle A+B+C = 180

Since they are in AP  

                  B = A+C /2

   = A+C = 180- B

  2B = 180 - B

B = 60 so B  be cant be least or highest  

so either A or C should be

so if A is highest  A = 3C

 So A+ C = 4C

So since A + C is 2B

        120 = 4C

C = 30

 A = 90

SO what ever either A or C the least angle should be 30
