Question

Two sides of a triangle are 15 cm and 20 cm. The perimeter of the triangle is 50cm. What is the third side?

Answer 1

Step-by-step explanation:

let the sides be a, b and c

a=15. b = 20. c =?

a+b+c = 50

15+20+c. =50

c = 50 — (15+20)

c = 50 — 35

c = 15 cm...

Answer 2

Answer:

it is simple bro/sis

perimeter is 50 cm

if 2 sides are given 15cm and 20 cm

so, 3rd side = 50-(15+20)

=50-35

=15

so the third side is 15 cm
