+11912 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?
+33661 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.
+11912 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
+33661 Correct rosala.
An isosceles triangle has exactly two sides the same length by definition (and the other side is usually called the base).
+11912 okay so the formula i wrote was correct!
Thank you Alan!I'll give u points for your answers!
+11912 Oops!sorry Melody i just wrote the incorrect name , ive just corrected it!Thanks for reminding me!i think in the tension of tomorrows exam i am not doing anything correctly!
