Question

note book m solve plz​

Answer 1

Explanation :

Let,

∆ABC Congruent ∆PQR

By properties of congruent triangles,

AB=PQ, BC=QR and AC=PR................... (1)

But, AC=3x+2 and PR=6x-13

Therefore,

3x+2 = 6x-13

-3x = -15

x = 5 .................................................. (2)

Now,

BC = 5x

= 5×5...........................from equation (2)

= 25

But,

QR = BC............................ from equation (1)

QR = 25 unit
