Given:
To find:
The exact value of cos(u-v) if both angles are in quadrant 3.
Solution:
In 3rd quadrant, cos and sin both trigonometric ratios are negative.
We have,
Now,
On further simplification, we get
Similarly,
Now,
Therefore, the value of cos (u-v) is 0.1872.
Because you wont add the wrong nubers together because 1/10 is .1 and 1/100 is .01

Answer:
The formula that represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A) is .
Step-by-step explanation:
We are given the area of an Equilateral triangle which is A = . And we have to represent the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).
So, the area of an equilateral triangle =
where, s = side of an equilateral triangle
A =
Cross multiplying the fractions we get;
Now. moving to the right side of the equation;
Taking square root both sides we get;
Hence, this formula represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).
