Step-by-step explanation:
Angle W is the corresponds as to angle C
it depends on what type of triangle is it a right triangle?
Answer: + =
Step-by-step explanation:
The standard form of equation of a circle is written in the form:
+ =
where a and b are the coordinates of the center and r is the radius.
All we need to do is to covert the given equation into this form, how do we do that?
We will achieve this by using the completing method of solving quadratic equation.
Firstly re - write the equation , that is
- 6x + -4y = 12
The next thing is to Complete the square for each of x and y
How do we do this ?
i. multiply the coefficient of x and y by 1/2
ii. square the results
iii. Add the result to both sides of the equation , that is
- 6x + - 4y + = 12 ++
The next thing is to write the Left hand side of the equation as a perfect square binomial and simplify the Right hand side. That is
+ = 25 , that is
+ =
Which is now in standard form of the equation of a circle.
Answer:
12 units
Step-by-step explanation:
To find the perimeter given vertices, find the distance from one point to another.
Step 1. Find the distance between (2, 3) & (5, 3)
Answer: 3 (in this case) because for 2 to get to 5, it’s 3 units
Step 2. Find the distance between (5, 3) & (5, 7)
Answer: 4 (in this case) because for 3 to get to 7, it’s 4 units
Step 3. Find the distance between (5, 7) & (2, 3)
Answer: 5
Step 3 explanation: In image.
Step 4. Add all the distances between the points.
3 + 4 + 5 = 12 units
The perimeter is 12 units
