Use the law of cosines to write an expression equivalent to b

andrezito [222]

Given:

A triangle ABC.

The given expression for b is:

$b=\sqrt{m+n-pq}$

To find:

The expression that is equivalent to b.

Solution:

According to the Law of Cosines,

$b^2=a^2+c^2-2ac\cos B$

It can be written as:

$b=\sqrt{a^2+c^2-2ac\cos B}$ ...(i)

We have,

$b=\sqrt{m+n-pq}$ ...(ii)

On comparing (i) and (ii), we get

$m=a^2$

$n=c^2$

$p=2ac$

$q=\cos B$

Therefore, the required values are $m=a^2,n=c^2,p=2ac,q=\cos B$ .

s2008m [1.1K]

The answer to this problem is 16.

To solve we must follow the order of operations.

8/2 is 4.

2+2 is 4.

So, now we multiply 4(4) and will get 16 as the answer

So, 16 is the answer.
