Answer:
The center is (7,-4) and the radius is 3
Step-by-step explanation:
(x – 7)^2 + (y + 4)^2 = 9
The equation of a circle can be written as
(x – h)^2 + (y - k)^2 = r^2
where (h,k) is the center and r is the radius
Rewriting the original equation
(x – 7)^2 + (y - - 4)^2 = 3^2
The center is (7,-4) and the radius is 3
x = 36
pentagon has 5 sides . The formula n/360 gives you the measure of each angle in a regular polygon. So in this case n ( stands for number of sides) is 5. Sum of exterior angle of a any polygon is 360. The measure of 1 exterior angle is given. It is 2x.
Now using ALGEBRAIC EXPRESSIONS we can write it as 5/360 = 2x
which is 72=2x
which is 72/2 = x
which is 36 = x
so x = 36.
Multiply 3 times 4 which gives you 12 then multiply that by 65 and your answer is 780
Answer:
Decompose the figure into two rectangles and add the areas.
Step-by-step explanation:
We can draw a vertical line segment from the smaller section of the rectangle straight down. This would cut the rectangle into 2 smaller rectangles. We can then find the area of each rectangle and add them to find the area of the composite figure.
