if slope is 4/3 when x=4 ... y=3 Therefore hipotenuse is 5 (it´s a 3,4,5 triangle). Then, if the legnth of the hipotenuse is 30. It´s 6 times longer than our sample triangle (3,4,5). So the base of the triangle, will also be 6 times longer than in our sample (3*6=18). Sample triangle: 3,4,5 (as le...
