    let x be the length of the third side x must be greater than 17 - 8 = 9 units because if it were 9 units, then you'd have a straight line. If it were smaller than 9 units, then you wouldn't have a triangle. x also must be smaller than 17+8 = 25 units to ensure you will have a closed/complete triangle

    so x > 9 and x < 25 9 < x and x < 25 9 < x < 25

    drawing a picture helps a lot if you don't/can't see this a better way is to use rigid sticks to see this
