Question

two equal sides of a triangle are each 5meters less than twice the third side. if the perimeter of triangle is 55meters find the length of its sides​

Answer 1

Step-by-step explanation:

Let the third side be x m.

Then the two equal sides are of length (2x−5) m.

Perimeter of triangle = 55 m.

⟹x+(2x−5)+(2x−5)=55

⟹5x−10=55

⟹x=13

Hence, the length of the triangle's sides are 13m, 21m and 21m.

Answer 2

Step-by-step explanation:

let the equal side = x

third side = 3x+5

x+x+3x+5=55

5x=50

x=10

10

35
