I could be wrong.....i m not sure sorry??? The point which we need to find is on x axis which means y=0....okk???now let the coordinates be(x,0)...this point is eqidistant from those points so....u can use mid point formula i.e. x1 + x2 /2 = x so,.....7+3 /2=x so....x will be 5...... I don\'t know the answers plz ask from your teacher..... |
