Triangle LMN is a right triangle. True or false

False

Step-by-step explanation:

5^2+13^2=14^2

25 +169=196

194 ≠ 196

They’re not equal meaning it’s not a right triangle. Sorry for my first answer. I was supposed to use the Pythagorean theorm

LMN is an acute triangle not right triangle

Step-by-step explanation:

by using pythagoras thoerem

a²+b²=c²

putting values

5²+13²=14²

25+169=194

194=196 so it is not a right angled triangle

if a²+b²=c² then it is right triangle

but if a²+b²<c² then it is acute triangle

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
