  1. (2x + 15⁰) + (x + 6⁰) + (3x + 25⁰) = 180⁰

    2x + 15⁰ + x + 6⁰ + 3x + 25⁰ = 180⁰

    2x + x + 3x = 180⁰ - 15⁰ - 6⁰ - 25⁰

    6x = 134⁰

    x = 134⁰/6

    x = 22 1/3 ⁰


  2. sum of angles in a triangle is 180, hence 2x+15+x+6+3x+25=180. Solve for x.

  3. i answered this question about 1/2 hr ago - if u don't want to accept the work of a teacher and mathematician - a master teacher , fine!

  4. 2x+15 + x+6+ 3x+25=180

    x=22.333...

    Substitute the value of x for each side of the triangle.

  5. 2x+15 + x+6 + 3x+25 = 180

    6x+46 = 180

    6x = 180-46

    6x = 134

    x = 22.33

    2(22.33)+15 = 59.66

    22.33+6 = 28.33

    3(22.33)+25 = 91.99

    59.66 , 28.33 , 91.99

  6. The ans is2x+15+x+6+3x+25=180

                    6x+46=180

                    6x=180-46

                    6x=  134

                    x=22.3333

  7. [2x + 15] + [x + 6] + [3x + 25] = 180 degrees {sum of angles of a triangle)

    therefore, 6x + 46 = 180 degrees

    therefore, 6x = 180 - 46 = 134

    therefore x = 134/6 = 67/3

    Sub x = 67/3 into the [x] of each given angle and you'd get: 179/3 degrees, 85/3 degrees and, 92 degrees.
