the
Find the length of each of the equal sides of the isosceles triangle
(ii) Perimeter = 55 cm, unequal side = 15 cm​

Answer 1

Answer:

AC=20cm, AB=20cm and BC=15cm

if you are satisfied then pls tell me if not then also pls tell me

Answer 2

Answer:

Answer is 20 cm

Step-by-step explanation:

Given: Perimeter=55 cm side =15 cm Perimeter of a triangle =sum of all sides =

$side1 + side2 + side3$

=

$15 + side1 + side2$

$55 - 15 = side1 + side2$

$40 = side1 + side2$

Now, Given triangle is isosceles Hence, side1=side2 =

$perimeter \div 2$

=

$40 \div 2$

=20 cm side1 =side2 =20 cm
