Find the length of the diagonal ad in the pentagon abcde shown in the coordinate plane.

a. √ 89 units
b. 5 units
c. √ 73 units
d. √ 41 units

units.

Therefore, Option C is correct.

Step-by-step explanation:

We have given a pentagon ABCDE

We need to calculate its length

That means we have to find the distance of AD

So, coordinates of A(1,6) and D(4,-2)

Using distance formula:

Here,

On substituting the values we will get:

On simplification:

.

Hence, the length of AD is   units.

Therefore, Option C is correct.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
