The sum of the interior angles of a polygon is 14 × 180 . Work out the number of sides of the polygon.
Answer:
Number of sides of the polygon = 16
Step-by-step explanation:
Sum of the interior angle of a polygon = (n - 2) × 180°
Here, n = Number of sides of the polygon
If sum of the interior angles = 14 × 180°
Therefore, (n - 2) × 180° = 14 × 180°
(n - 2) = 14
n = 14 + 2
n = 16
Number of sides of the polygon = 16

find the sine and cosine of a 60° angle
find the sine and cosine of a 30° angle
Answer:
Using the 30-60-90 triangle to find sine and cosine
sin(60 degrees) = 2√3 4.
sin(60 degrees) = √3 2.
sin(30 degrees) = 2 4.
sin(30 degrees) = 1 2.
cos(60 degrees) = 2 4.
cos(60 degrees) = 1 2.
cos(30 degrees) = 2√3 4.
cos(30 degrees) = √3 2.
Ursula and Velda live 4 km apart. They leave their homes at the same time, walking towards each other. If Ursula walks at a rate of 400 m/h, and Velda walks at a rate of 600 m/h, how far apart are they 15 minutes before they meet (in m)?
Answer: 250 m
Step-by-step explanation:
Given
Distance between Ursula and Velda house is 4 km or 4000 m
Ursula walks at the rate of [tex]400\ m/h\ or\ \frac{20}{3}\ m/min[/tex]
Velda walks at the rate of [tex]600\ m/h\ or\ 10\ m/min[/tex]
Time taken by them to cover 4000 m is
[tex]\Rightarrow \dfrac{4000}{400+600}=4\ h\ or\ 240\ min[/tex]
Distance covered by them 15 min before they meet
Ursula [tex]=\frac{20}{3}\times 225=1500\ m[/tex]
Velda [tex]=10\times 225=2250\ m[/tex]
The total length covered by them is [tex]=1500+2250=3750\ m[/tex]
They are [tex]4000-3750=250\ m[/tex] apart before they meet

IM TYPEING RANDOM WORDS CUZ IT SAYS ITS TOO SHORTTTTTTTTTTT
can somebody help!! fastest and correct answer gets brainly!
Answer and Step-by-step explanation:
We know that the triangle got dilated by a scale factor of 4. This means that the sides are multiplied by 4.
So 6 becomes 24, and 8 becomes 32.
Now, we find the area of the triangle.
24 × 32 = 768
768 ÷ 2 = 384.
The answer is D. 384 square cm.
The answer IS NOT B. 96 square cm, because you don't multiply the area of the triangle before the dilation. The dilation occurs first, and then you have to find the area.

A seagull is flying 11 meters above the water. Directly below the bird, a fish is swimming 31 meters under the surface. What is the total difference in distance between the bird and the fish? A 11 B 20 C 31 D 42
Answer: D. 42 meters
Step-by-step explanation:
In calculating the distance between the seagull and the fish, you need to add their distances from sea level as this shows their distance from the sea and then from each other:
Seagull is 11 meters above the water
Fish is 31 meters below the water
Total difference
= Fish + Seagull
= 31 + 11
= 42 meters

If h:k = 2:5, x:y=3:4 and 2h+x:k+2y = 1:2, find the ratio h-x: k-y.
Given:
[tex]h:k=2:5,x:y=3:4,2h+x:k+2y=1:2[/tex]
To find:
[tex]h-x:k-y[/tex]
Solution:
We have, [tex]h:k=2:5[/tex] and [tex]x:y=3:4[/tex].
Let the values of h and k are 2a and 5a respectively.
Let the values of x and y are 3b and 4b respectively.
We have,
[tex]2h+x:k+2y=1:2[/tex]
It can be written as
[tex]\dfrac{2h+x}{k+2y}=\dfrac{1}{2}[/tex]
[tex]\dfrac{2(2a)+(3b)}{5a+2(4b)}=\dfrac{1}{2}[/tex]
[tex]\dfrac{4a+3b}{5a+8b}=\dfrac{1}{2}[/tex]
[tex]2(4a+3b)=1(5a+8b)[/tex]
On further simplification, we get
[tex]8a+6b=5a+8b[/tex]
[tex]8a-5a=8b-6b[/tex]
[tex]3a=2b[/tex]
[tex]a=\dfrac{2b}{3}[/tex]
Now,
[tex]h-x:k-y=\dfrac{h-x}{k-y}[/tex]
[tex]h-x:k-y=\dfrac{2-3b}{5a-4b}[/tex]
[tex]h-x:k-y=\dfrac{2\times \dfrac{2b}{3}-3b}{5\times \dfrac{2b}{3}-4b}[/tex]
[tex]h-x:k-y=\dfrac{\dfrac{4b}{3}-3b}{\dfrac{10b}{3}-4b}[/tex]
On further simplification, we get
[tex]h-x:k-y=\dfrac{\dfrac{4b-9b}{3}}{\dfrac{10b-12b}{3}}[/tex]
[tex]h-x:k-y=\dfrac{-5b}{-2b}[/tex]
[tex]h-x:k-y=\dfrac{5}{2}[/tex]
[tex]h-x:k-y=5:2[/tex]
Therefore, the ratio [tex]h-x:k-y[/tex] is [tex]5:2[/tex].

Which is the equation of the line in slope-intercept form?
A) y = -3x - 2
B) y = 3x + 2
C) y=-1/3x+2
D) y= 1/3x-2
Answer:
A). y = -3x - 2
Step-by-step explanation:
Since the line is going downwards from left to right, we know that it is a negative line.
Slope equals rise/run. If you take any two points, it goes down 3 and 1 right. You don't put 1 so it's simply just -3x.
The line crosses the y axis at -2.

Answer:
x = -7
Step-by-step explanation:
The interior angles of a triangle should all add up to 180 degrees.
So, we set the equation up as:
(x + 52) + 75 + 60 = 180
Then solve for x:
(x + 52) + 75 + 60 = 180
(x + 52) + 135 = 180
x + 52 = 180 - 135
x = 45 - 52
x = -7

I really need help with the radius,diameter and area off circles and halfcircles
Answer:
Radius refers to the distance between the center of the circle to any point of the circle
Diameter refers to the distance between any two points on the circle passing through the center of circle, it is also equal to radiusx2
Area of circle = πr², where π is a constant (≈3.14159), r is the radius
Halfcircles is basically half of the circle. It has the same radius and diameter as it's full circle but the area of the halfcircle is equal to half of the area of the full circle.

A 12.5-foot ladder is leaning against the side of a house. If the ladder is resting 12 feet off the ground, how far is the ladder from the house?
A. 2 feet
B. 3.5 feet
C. 6.25 feet
D. 7 feet
Answer:
B. 3.5 feet
Step-by-step explanation:
The part leaning against the wall is the hypotenuse while the height of the ladder off the ground is the opposite and the distance of the ladder from the house is the adjacent side.
Given the following data;
Hypotenuse = 12.5 ft
Opposite = 12 ft
To find the adjacent side, we would use the Pythagorean theorem;
Hypotenuse² = opposite² + adjacent²
Substituting into the formula, we have;
12.5² = 12² + adjacent²
156.25 = 144 + adjacent²
Adjacent² = 156.25 - 144
Adjacent² = 12.25
Taking the square root of both sides, we have;
Adjacent = 3.5 feet.
Therefore, the distance of the ladder from the house is 3.5 feet.
