Question

In a right angled triangle A LMN, M-90°. If/ (LM) = 12cm and / (LN) = 20cm, Find the length of seg MN​

Answer 1

Answer:

16

Step-by-step explanation:

given,

LM= 12 cm

LN = 20 cm

by PGT

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

(20)^2= (12)^2+ (mn)^2

400= 144+ MN^2

400-144= (MN)^2

256= MN^2

16= MN
