If 7x – y + 3 = 0; x + y – 3 = 0 are tow sides of an isosceles triangle and the third side passes through (1, 0) then the equation of the third side is

So here we used the concept of the triangles, and the equations of the lines to solve this problem. We know that the equation of a straight line in slope-intercept form is given as y = mx+c, so we used that here. So the equation of the third side is x + 3y - 1 = 0.

Consider two different ammeters in which the deflections of the needle are proportional to current. The first ammeter is connected to a resistor of resistance R subscript 1 end subscript and the second to a resistor of unknown resistance R subscript x end subscript. At first the ammeters are connected in series between points A and B [as shown in fig. a)]. In this case the readings of the ammeters are n subscript 1 end subscript and n subscript 2 end subscript. Then the ammeters are connected parallel between A and B as shown in fig.(B) and indicated n subscript 1 end subscript superscript ´ end superscript and n subscript 2 end subscript superscript ´ end superscript. Determine the unknown resistance R subscript x end subscript of the second resistor.
