An isosceles triangle with base 12mm and perimeter 28mm
olga55 [171]

Answer:

Side lengths of 12,8,8

Step-by-step explanation:

In an isosceles triangle the base is different from the other 2 sides which are the same so

28=12+2x (x being the side of the repeat sides)

14=6+x (divide both sides by 2)

8=x (subtract 6 from both sides) so

Side lengths of 12,8,8

The combined land area of the countries a and b is 177 ,973 square kilometers. country a is larger by 773 square kilometers. det
Troyanec [42]
Let b = x

a = x + 773

x + <span>x + 773 = 177973

2x + </span><span>773 = 177973

2x = </span>177973<span> - 773

2x = 177200

x = </span>177200<span>/2

x = 88600

The other is x + 773,  =  8860</span>0<span> + 773 = 89373

Each country is </span><span>88600</span> and 89373 square kilometers.
