There's a relatively easy way to solve problems of this nature. You determine the contribution made if the only contributor is the one that contributes the least.

A chicken has the least number of feet, so 24 chickens will contribute 48 feet.

Now, you consider the change in contribution made by substituting a larger contributor. Each pig that replaces a chicken will add 2 feet to the total.

Consider how many feet need to be added, and thus how many larger contributors are needed. 80 -48 = 32 feet need to be added, so 32/2 = 16 of the animals need to be pigs.

There are 16 pigs and 8 chickens.

Suppose a triangle has two sides of the length 2and 3 and that the angle between these two sides is 60 what is the length of the

Usimov [2.4K]

Let the given sides be "a" and "b" and the unknown side be "c". The Law of Cosines tells you
.. c^2 = a^2 +b^2 -2ab*cos(C)
.. c^2 = 2^2 +3^2 -2*2*3*cos(60°)
.. c^2 = 7
.. c = √7 ≈ 2.6458

The third side of the triangle is √7, about 2.6458.
