Question

the three angle of a triangle the second one is one third of the first and the third angle is 26 degree more than the first angle find all the three angle of the triangle​

Answer 1

Step-by-step explanation:

let the first angle be x

Therefore, the second angle will be  x/3

         and third angle will be  x+26

According to the question,

                              x + x/3 + x+26 = 180 ( angle sum property of a  triangle)

                            7 x/3 = 180-26

                            7 x = 154 * 3

                            x =462 / 7

                            x = 66  

Therefore, the three angles are 66, 22, 92 .
