Question

In LMN, m = 90° & LM = 6cm &
MN =8cm then find LN=?

​

Answer 1

Answer:

10cm

Step-by-step explanation:

Sol:

In Triangle LMN, using Pythagoras theorem

p^2 + b^2 = h^2

or, (LM)^2 + (MN)^2 = (LN)^2

or, (6)^2 + (8)^2 = (LN)^2

or, 36 + 64 = (LN)^2

or, 100 = (LN)^2

or, $\sqrt{100}$ = LN

or, LN = 10cm
