Step-by-step explanation:
Given expression is,
To prove this identity we will take the right side of the identity,
[Since
]
= cot A
Hence right side of the equation is equal to the left side of the equation.
To find the length of a line given two points, we are going to use the distance formula, which is defined below:
( and
are the two points)
The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:
- Substitute values into formula
- Combine like terms and then simplify
to 0
- Compute
- Compute
The length of DC is 3.
