Question

the length of equal sides of an isosceles triangle is 16.7 cm find the length of third side if it's perimeter is ,50 cm.​

Answer 1

Answer:

subtract 2×length of equal sides from the perimeter.

Answer 2

Answer:

16.6 cm

Step-by-step explanation:

perimeter of a triangle= a+b+c

since this is an isosceles triangle, a=b= 16.7 cm

to find c, we need to subtract the sum of the two equal sides from the perimeter

that is: 50- 16.7 + 16.7

= 16.6 cm
