Do the lengths : 5 cm 12 cm 13 cm make a unique triangle?

a=5,b=12,c=13

s=  1/2(a+b+c)=15

Area of the triangle, A =  

s(s−a)(s−b)(s−c)

A=  15(15−5)(15−12)(15−13)

A= 30 cm2

Let p be the length of perpendicular. Then,

A= 1/2 ×13×p

Therefore,

1/2×13×p=30

p= 60/13 cm

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
