62/15=x+x+4/3

62/15=2x+4/3

62/15-4/3=2x

(62-20)/12=2x

42/15/2=x

42/15×1/2=x

Answer 2

Answer:

7/5 cm

Step-by-step explanation:

Base of isosceles triangle = 4/3 cm

Perimeter of triangle = 62/15 cm

Let the length of equal sides of triangle be x.

According to the question,

4/3 + x + x = 62/15 cm

⇒ 2x = (62/15 – 4/3) cm

⇒ 2x = (62 – 20)/15 cm

⇒ 2x = 42/15 cm

⇒ x = (42/30) × (½)

⇒ x = 42/30 cm

⇒ x = 7/5 cm

The length of either of the remaining equal sides are 7/5 cm.
