the measures of the interior angles of a triangle are x,y and 2x respectively. if the triangle is isosceles, what is one possible measure of an angle of this triangle, in degrees?

  • math -

    if x and y are the equal angles,
    then
    x+y+2x = 180
    x+x+2x=180
    x = 45

    angles: 45, 45, 90

    if the x and 2x are the equal angles
    then
    x + y + 2x = 180
    x+2x+2x=180
    x = 36

    angles:
    36, 72, 72
