Question

cm and Q.29 The Perimeter of triangle is (17x - 12) cm. It's two sides are (x - 5) * c * l (7x+5) cm long What is the length of it's third side​

Answer 1

★AnSwEr:-

Perimeter = (17x - 12) cm

1st side = x - 5

2nd = 7x + 5

3rdside = perimeter - (1st + 2nd side )

so,

x - 5 + 7x + 5

=8x

Now,

17x - 12 - 8

= 9x - 12 is the 3rd side
