Answer 2

Answer:

ln = 10 cm

Step-by-step explanation:

∆LMN will be a right angled triangle, Since one of the angle is 90

Therefore,

We can use Pythagoras Theorem Here

i.e.

${h}^{2} = {p}^{2} + {b}^{2}$

Since, (p)LM = 6 cm

(b)MN = 8 cm

(h)LN = ?

Now,

Putting values in Pythagoras Theorem-

${h}^{2} = {6 }^{2} +{8 }^{2} \\ {h}^{2} = 36 + 64 \\ {h}^{2} = 100 \\ \\ h = \sqrt{100} \\ h = 10$

Therefore,

(h)LN = 10 cm
