Question

the side of triangle are 13 cm 17 cm and 20cm find the length of the perpendicular from the apposite vertex to the side of length 20 cm​

Answer 1

Answer:

Step-by-step explanation:

     =  

                       =  

        Let A be the area of the given triangle, then

               A      =  

                       =  

                       =  = 30 cm2

        Let p be the length of the perpendicular from vertex D on the side BC, then

              A       =  

            2A       = 13p

        2 × 30 = 13P  

        Hence, length of perpendicular from the opposite vertex to the side whose length is 13 cm is  cm
