the triangle is 56 meter, find the length of its side
Two supplementary angles differ by Pind the anges​

Answer 1

Answer:

Step-by-step explanation:

Let the length of third side be a units

length of equal sides = (2a -5) units

now, perimeter = 55

⇒a + (2a-5) +(2a-5) = 55

⇒5a =65

⇒a =13

so length of sides are 13 m, 21 m and 21 m
