A. Find the mZAOC
B. Find the mZBDC
C. Find the mZACD
AB is a a straight line and AC is a tangent to the circle, then the
(a) ∠AOC = 58°
(b) ∠BDC = 32°
(c) ∠ACD = 148°
According to the figure,
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
What is the tangent of the circle?It is the line which intersects the circle exactly at one point.
(a) Find m ∠AOC
Sum of three angles of a triangle is = 180°
So, in Triangle AOC = 180°
∠A + ∠O + ∠C = 180°
See in Image, ∠A and ∠C are 90° and 32°
∠A + ∠O + ∠C = 180°
We can substitute these values,
∠O = 180 - ∠A - ∠C
∠O = 180 - 90 - 32
∠O = 58°
∠AOC = 58°
(b) ∠BDC is a parallelogram,
So,
Opposite angle is equal,
∠BDC = ∠ABC
∠BDC = 32° ( since ∠ABC = 32° )
(c) Find m ∠ACD
Sum of three angles of a triangle is = 180°
So, in Triangle ACD = 180°
∠A + ∠C + ∠D = 180°
See in Image, ∠A and ∠D are 90° and 32°
∠A + ∠D + ∠C = 180°
We can substitute these values,
∠C = 180 - ∠A - ∠D
∠C = 180 - 90 - 32
∠C = 58°
Now,
∠ACD = 90 + 58
∠ACD = 148°
Therefore,
The circumference of tangent to the circle,
(a) ∠AOC = 58°
(b) ∠BDC = 32°
(c) ∠ACD = 148°

The area of the sector is 250 units².
The area of the sector is 100 units².
The area of the sector is more than half of the circle’s area.
Answer:
1, 3, 5
Step-by-step explanation:
just took the edge.
The area of the sector is 250 units². Therefore, the correct option is option A among all the given options.
What is sector of circle?A circle's sector is a pie-shaped portion made up of the arc and its two radii. At both ends of the arc, when a section of the circle's circumference (also called as an arc) and two of its radii meet, a sector is produced. A sector of such a circle resembles a piece of pizza or a pie in shape.
A circle ranks among the most ideal shapes in geometry. The simplest geometric shape is that of a circle's sector. It has a number of its own components. such as sector, segmentation, circumference, segment, and diameter. The area of the sector is 250 units².
Therefore, the correct option is option A.

Ms. Geiger made 100 cupcakes. 60/100 were chocolate, 2/10 were vanilla, and the rest were red velvet. What fraction of the cupcakes were red velvet?
Answer:
2/10
Step-by-step explanation:
Ms. Geiger made 100 cupcakes.
a) Number of chocolate
60/100 were chocolate
= 60/100 × 100 = 60 chocolate cup cakes
b) Number of vanilla
2/10 were vanilla
Hence:
2/10 × 100 = 20 vanilla cup cakes
c) the rest were red velvet.
Number rod red velvet = 100 - (60 + 20)
= 100 - 80
= 20 velvet cupcakes
What fraction of the cupcakes were red velvet?
Converting to fraction
Number of velvet cupcakes/Total number of cakes
= 20/100
= 2/10
What is the image of the point (-8,3)(−8,3) after a rotation of 270^{\circ}270
∘
counterclockwise about the origin?
Given:
The point is (-8,3).
To find:
The image of the given point after a rotation of 270 degrees counterclockwise about the origin.
Solution:
If a point is rotated 270 degrees counterclockwise about the origin, then the rule of rotation is:
[tex](x,y)\to (y,-x)[/tex]
Using this rule, we get
[tex](-8,3)\to (3,-(-8))[/tex]
[tex](-8,3)\to (3,8)[/tex]
Therefore, the image of the given point after a rotation of 270 degrees counterclockwise about the origin is (3,8).
Sachin wants to create two rectangular enclosures in his backyard with fencing for his pet rabbit and dog.
He wants the two enclosures to have equal areas and to share one common side. He has 30 m of fencing
to use and wants to maximize the total area of both fenced in enclosures. Round your final answer to 2
decimal places, where necessary. Determine the dimensions of one rectangular enclosure.
Answer:
perimeter of rectangular enclosures =30m
2(l+b)=30m
l+b=30/2
l=15-b..........1
now
since it has equal area their l and breadth too are equal
new
perimeter =15/2=7.5m
the dimensions of one rectangular enclosure is 7.5m.

Which equation can be used to solve for x, the increase in side length of the square in inches?
x2 + 4x – 81 = 0
x2 + 4x – 65 = 0
x2 + 8x – 65 = 0
x2 + 8x – 81 = 0
Answer:
x2 + 8x – 65 = 0
Step-by-step explanation:
Complete question
A square picture with a side length of 4 inches needs to be enlarged. The final area needs to be 81 square inches. Which equation can be used to solve for x, the increase in side length of the square in inches? x2 + 4x – 81 = 0 x2 + 4x – 65 = 0 x2 + 8x – 65 = 0 x2 + 8x – 81 = 0
Given the initial side length = 4in
Initial area = L²
L is side length of the square
Initial area = 4²
Initial area = 16 square inches
Area of the enlarged square = 81 square inches
To get the constant term of the expression, we will find the difference in the areas
Difference = 85 - 16
Difference = 65 square units
The coefficient of x will be the 2 *initial area of the square
Given the standard form of an expression as
ax^2 + bx + c
a = 1, b = 2*4 = 8, c = -65
Substitute
x^2 + 8x - 65
This gives the required expression

Answer:
75.4m²
Step-by-step explanation:
The shape shown is a cylinder
The volume of a cylinder can be calculated using this formula:
[tex]V=\pi r^2h[/tex]
where r = radius and h = height
The cylinder shown has a radius of 2m and a height of 6m
Using this information we plug in the values into the formula
[tex]V=\pi 2^26\\2^2=4\\4\pi =12.56637\\12.56637*6=75.39822[/tex]
So the area of the cylinder is 75.39822
Our final step is to round to the nearest hundredth
The final answer would be 75.4m²
