Answer/Step-by-step explanation:
✔️A = 180° - (50° + 90°) (sum of triangle)
A = 40°
✔️Find a:
Reference angle = 50°
Opposite = 17
Adjacent = a
Therefore, using trigonometric ratio, we have the following:
Tan 50 = 17/a
a = 17/tan 50
a = 14.3 (nearest tenth)
✔️Find c using Pythagorean Theorem:
c² = a² + b²
c² = 14.3² + 17²
c = √493.49
c = 22.2 (nearest tenth)

Answers
Answer:
{16, 17, 18, 19, 20, 21, 22,23, 24, 25}
Step-by-step explanation:
Given the set A={a|a an even number and 15< a< =25}
The inequality 15< a< =25 mean the set A consists of all the values between 15 and 25 with 25 inclusive (due to presence of the equal to sign)
Hence the required set A are {16, 17, 18, 19, 20, 21, 22,23, 24, 25}
Note that 15 is excluded from the set of number since 15<a i.e a > 15

how can you find the area of a circle? give me a good explanation please, ty!
Answers
Answer:
The area of a circle is pi times the radius squared (Area = pi radius²).
Step-by-step explanation:
The circumference of a circle is the linear distance of a circle's edge. It is the same as the perimeter of a geometric figure, but the term 'perimeter' is used exclusively for polygons.
The following equation describes the relation between the circumference and the radius R of a circle:
C = 2πR
Where π is a constant approximately equal to 3.14159265..
How to find the circumference of a circle
Determine the radius of a circle. Let's assume it's equal to 14 cm.
Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm.
You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm².
Finally, you can find the diameter - it is simply double the radius: D = 2 * R = 2 * 14 = 28 cm.
Use our circumference calculator to find the radius when you only have the circumference or area of a circle.
Answer:
Use this formula: A = π r²
Step-by-step explanation:
A = π r²
What does A = π r² mean? :
(Area = Pi x Radius²)
π = Pi (3.14)
² = squared

how many perfect square are there between 1,000,000 and 9,000,000?
Answers
Answer:
1999
Step-by-step explanation:
The square root of 1,000,000 = 1,000.
The square root of 9,000,000 = 3,000.
This means that the number of perfect square will be every number from 1,000^2 to 3,000^2. To find how many numbers that is, just do 3000-1000 = 2000, and then subtract one because otherwise you would be counting the 3000^2 which you don't want to do (it asks how many perfect squares are between the two numbers).
2000 - 1 = 1999.
The number of perfect squares between the values 1,000,000 and 9,000,000 would be 1999
Taking the square root of the boundaries :
√1,000,000 = 1000√9,000,000 = 3000The number of perfect squares would be :
[(√9,000,000 - √1,000,000) - 1]
[3000 - 1000] - 1
2000 - 1
= 1999
Hence, the number of perfect squares would be 1999.

Step-by-step explanation:
The problem above requires the use of mathematical operation with mixed fractions. In order to do this, you have to convert the mixed fractions into improper fractions first.
Let's convert.
[tex]3\frac{1}{2}[/tex] = [tex]\frac{7}{2}[/tex][tex]1\frac{2}{3}[/tex] = [tex]\frac{5}{3}[/tex]Next, you have to multiply the fractions by multiplying the numerators with each other and the denominators with each other.
Let's solve.
[tex]\frac{7}{2}[/tex] x [tex]\frac{5}{3}[/tex] = [tex]\frac{35}{6}[/tex]Since [tex]\frac{35}{6}[/tex] is an improper fraction and the choices above are mixed fractions, you have to convert it.
Let's convert.
[tex]\frac{35}{6}[/tex] = [tex]5\frac{5}{6}[/tex]Therefore, the answer is [tex]5\frac{5}{6}[/tex]

Find the equation of a line perpendicular to x=−4 that contains the point (−3,4). Write the equation in slope-intercept form.
Answers
Answer:
y=4
Step-by-step explanation:
We recognize x=−4 as a vertical line, so its perpendicular will be horizontal. The equation of the horizontal line containing the point (−3,4) is given by y=4.
The slope-intercept form of a line perpendicular to x=−4 that contains the point (−3,4) is y = 4.
What is the slope of a line that is perpendicular to the other line?The slope-intercept form of a line is y = mx + c.
Here, m = slope and c = y-intercept of the line.
The equation of the given line is x = - 4
Therefore, the given line is a vertical line.
Now, the line that is perpendicular to the line x = - 4, is a horizontal line.
Now, the horizontal line that passes through the point (- 3, 4) is y = 4.

Find the measure of CD.
Round to the nearest tenth.
mCD= [?]
Answers
Answer:
The arc CD is: 114.64°
Step-by-step explanation:
The given triangle inside the circle, we can get the trigonometric ratio such as
sin x = opposite / hypotenuse
Here:
The opposite side of angle x = 36.7/2
The hypotenuse = 21.8
Thus,
sin x = [36.7/2] / [21.8]
sin x = 18.35 / 21.8
sin x = 0.8417
x = arc sin (0.8417)
x = 57.32°
Thus, the angle formed at the center by CD is:
2 x 57.32 = 114.64°
Therefore, the arc CD is: 114.64°
Answer:
The arc CD would be 114.6°
We use- sin x = opposite / hypotenuse
In the problem the opposite side of angle x = 36.7/2 and the hypotenuse = 21.8
So:
sin x = [36.7/2] / [21.8]
sin x = 18.35 / 21.8
sin x = 0.8417
x = arc sin (0.8417)
x = 57.32°
So the angle formed at the center by CD would have to be 2 x 57.32 = 114.64°
BUT, it says to round to the nearest tenth, so the answer would therefore, the arc CD is: 114.6°
