Two equal sides of a triangle are each 5 metres less than the twice the third side. if the perimeter of the triangle is 55 metres, find the
class 8 question

The sides are 13, 21, & 21 meters

Step-by-step explanation:

Let x represent the length of the base.  Then the congruent side lengths are 2x - 5.

Perimeter is the sum of the sides so

(2x - 5) + (2x - 5) + (x) = 55

                      5x - 10 = 55

                       5x       = 65

                         x       = 13

The length of the base is 13 meters.

The congruent side lengths are 2(13) - 5

                                                  =  26  - 5

                                                  =  21

ome people is not even worth it to even try it in the air.

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
