The base of an isosceles triangle is 4/3 cm . The perimeter of the triangle is 4 2/15 cm . What is the length of either of the remaining equal sides?

If it's an isosceles triangle the other two sides are the same length, call it x. So the perimeter is given by
2x + 4/3. This must equal 4 2/15 or 62/15
2x + 4/3 = 62/15
2x + 20/15 = 62/15
I'll leave you to take it from there rosala.
so we would do the rest like
2x + 20/15 = 62/15
2x = 62/15 - 20/15
2x= 42/15
x=42/15 ÷ 2
x = 42/15 * 1/2
x=21/15
x=7/5
x= 1 2/5 ANSWER
Thank you Alan for helping me!Just one thing to ask!
Whats the perimeter of an isosceles triangle!i mean whats its formula?
Is it
P=b + s + s

Correct rosala.
An isosceles triangle has exactly two sides the same length by definition (and the other side is usually called the base).
okay so the formula i wrote was correct!
Thank you Alan!I'll give u points for your answers!
