Question

the base of isoceles triagle is 4/3cm the perimter of the triangle is 4 2/15 what is the length of either of the remaining equal sides

Answer 1

here both step sides are equal and let the both side be x and x and their sum is x+x is 2x. now base is 4/3 and perimeter is 42/15. now , 2x+4/3=42/15. 4+6x =42/15 by cross multiplication. 15( 4+6x) = 126. 60+90x=126. 90x= 66 x=66/90. x=11/15 and hence both the equal side of isoceles triangle is 11/15 ans.
