Question

3 The perimeter of
triangle is 49cm . The one
side is 7.com longer than the other and
5cm shorter thenthe third. Find the length
of each side of the triangle.​

Answer 1

: REQUIRED ANSWER

$\implies$ let the third side = x

$\implies$ one side = x - 7

$\implies$ another side = x - 5

$\implies$ we know that , perimeter of a triangle = sum of all triangle

$\implies$ 49 cm = x + x - 7 + x + 5

$\implies$ 49 = 3 × -2

$\implies$ 47 = 3x

$\implies$ 47/3 = x

$\implies$ 17 = x

$\implies$ one side = 17 cm

$\implies$ second side = x - 7

$\implies$ 17- 7

$\implies$ 10 cm

$\implies$ Third side = x + 5

$\implies$ 17 + 5

$\implies$ 22 cm

Answer 2

Step-by-step explanation:

^____________________^

ANSWER ✍️

\implies⟹ let the third side = x

\implies⟹ one side = x - 7

\implies⟹ another side = x - 5

\implies⟹ we know that , perimeter of a triangle = sum of all triangle

• \implies⟹ 49 cm = x + x - 7 + x + 5

• \implies⟹ 49 = 3 × -2

• \implies⟹ 47 = 3x

• \implies⟹ 47/3 = x

• \implies⟹ 17 = x

• \implies⟹ one side = 17 cm

• \implies⟹ second side = x - 7

• \implies⟹ 17- 7

• \implies⟹ 10 cm

• \implies⟹ Third side = x + 5

• \implies⟹ 17 + 5

• \implies⟹ 22 cm
