Answer:
53°
Step-by-step explanation:
ΔABC is a right triangle (one of the angles is 90°).
You can use SOH-CAH-TOA to find an angle:
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
In this case, we want to find ∠A. We know the lengths of the opposite side and the hypotenuse. Therefore, we should use sine.
sin A = 12 / 15
m∠A = sin⁻¹(12/15)
m∠A ≈ 53°
Alternatively, you could use Pythagorean theorem to find the third side, then use either cosine or tangent to find m∠A.

53

PLEASE HELP I WILL MARK BRAINLIEST !!!! William looks from a height of 30 yards at the top of their apartment building. They line up the top of a flagpole with the curb of a street 40 yards away. If the
flagpole is 24 yards from the apartment building, how tall is tthe flagpole
Answer:
12 yards
Step-by-step explanation:
From. The picture attached, we could obtain the angle of elevation, θ from the curb of the street to the top of the building.
Using trigonometric relation :
Tanθ = opposite / Adjacent
Opposite = 30 yards
Adjacent = 40 yards
Tanθ = 30/40
θ = tan^-1(0.75)
θ = 36.869897°
Distance between curb of street and flagpole :
(40 - 24) yards = 16 yards
Let height of flagpole = h
Tanθ = opposite / Adjacent
Opposite = h yards
Adjacent = 16 yards
Tan36.869897 = h/16
0.75 = h / 16
h = 0.75 * 16
h = 12 yards

Step-by-step explanation: this is true because for 4.89 you would just add a 0 to make it 4.890
What is BD? Plzzzsss Helppp
Answer:
Step-by-step explanation:
since the two angles are the same we can set up a relationship between the two triangles and set them equal to each other and solve for X :) , as follows
SOH sin = Opp / Hyp
triangle 1 ) sin(Ф) = x / 12
triangle 2 ) sin(Ф) = x + 5 / 27
since sin(Ф) is the same for each triangle.. set those other sides equal to each other
x/12 = x+5 /27
now solve for x using your mad algebra skilz :P
27 / 12 = x + 5 / x
2 3/12 = x/x + 5/x
2 1/4 = 1 + 5/x
1 1/4 = 5/x
x = 5 / 1 1/4
x = 4 nice :)
So BD is then
4 + 4+5
so BD = 13

Nakato Nobuki, a Japanese artist, intends to withdraw $ 24,000.00 from his savings at the end of 5 years. Mr. Nobuki deposits $ 1,500.00 in savings annually and today has a balance of $ 8,000.00. What should be the savings interest rate for Nobuki to achieve his goals?
Answer:
The savings interest rate of Nakato Nobuki is 3 %
Step-by-step explanation:
Given;
Final amount of Nakato Nobuki, A = $ 24,000.00
time period of his investment, t = 5 years
principla amount, P = $ 1,500.00
The savings interest rate of Nakato Nobuki can be calculated on a simple interest basis.
A = P(1 + rt)
r is the savings interest rate
Substitute the given values and solve for r
24,000 = 1,500(1 + 5r)
24,000 = 1,500 + 7,500r
7,500r = 24,000 - 1,500
7,500r = 22,500
r = 22,500/7,500
r = 3 %
Therefore, the savings interest rate of Nakato Nobuki is 3 %

The dimensions of an ancient Egyptian rug are 6 feet by 8 feet. Priscilla is creating a drawing of the rug with the scale 4 cm = 1 ft. What are the dimensions of Priscila's drawing in cm?
Answer:
12 x 18 CM.
Step-by-step explanation:
Because 3 cm is 1 ft so if it is 4 you multiply that by 3 which equals 12 , and for 6 feet you multiply that by 3 cm and get 18. SO it is 12 x 18 cm.
The chess club has a budget of at least $300 that the members can spend for the field trip. There are 20 people in the chess club. They get a discount of $60 for transportation for the field trip. What is the minimum that each member
of the chess club can spend on the trip?
Answer:
$12
Step-by-step explanation:
We are told that there are 20 people in the chess club and each got a discount of $60 for transportation on the field trip.
Let the amount spent by each member is x
Since there are 20 of them and the budget is at least $300 and they get a discount of $60, it means that;
20x ≥ 300 - 60
20x ≥ 240
Divide both sides by 20 to get;
x ≥ 12
Thus, minimum amount each member can spend is $12.

What is the area of this
What is the volume???
Answer:
First find out the other side measurements. Then split the shape into seperate squares and find the area then add them all up.
Step-by-step explanation:
volume is length × width × height.
Answer:
240 cm cubed
Step-by-step explanation:
If you separate the shape into 2 figures, the first figures area is 180
and the second is 60.
180 + 60 = 240

Encontrar las coordenadas del centro y la longitud del radio de la circunferencia 9x²+9y²+18x-12+10=0
Answer:
Step-by-step explanation:
The standard form of equation of a circle is expressed as;
x^2+y^2+2gx+2fy+c = 0
The centre is at (-g, -f)
Given the equation'
9x²+9y²+18x-12+10=0
Divide through by 9
9x²/9+9y²/9+18x/9-12y/9+10/9=0
x^2+y^2+2x-4/3 y + 10/9 = 0
Compare
2gx = 2x
g = 1
2fy = -4/3 y
2f = -4/3
f = -4/6
f = -2/3
The centre is (-(-2/3), -1) = (2/3, -1)
for the radius
r = √f²+g²-c
r =√(-2/3)²+1²-10
r =√4/9 - 9
r = √(4-81)/9
r = √-77/9
Does the table below represents a linear function why or why not
Answer:
No, it's not linear function.
Step-by-step explanation:
The x value repeatedly adds 3.
So far its a linear function.
If you look at the y value, it does NOT have a pattern, therefore that means it is NOT a linear function.

In a right triangle the hypotenuse which is 16+9 =25 has to be the largest side. Since x is not the hyportenuse it has to be lower which only leaves one answer : 15
Answer:
Step-by-step explanation:
these are tough to solve , don't feel bad. soo part of the trick is that the two side set up similar triangles, then
16 / y = y /9 ( the two triangles
16* 9 = [tex]y^{2}[/tex]
144 = [tex]y^{2}[/tex]
12 = y
y is the length between the two triangles , so since we now know that part, we can solve the triangles.
lets use tan to solve one of the angles of the smaller triangle
TOA to remember how tan fits on a triangle
Tan = Opp / Adj
Tan(Ф) = 9/12
Ф = arcTan(9/12)
Ф = 36.869897
knowing that we can solve for x
use CAH cos = Adj / Hyp
Cos(36.869897) = 12 / Hyp
Hyp = 12/ Cos(36.869897)
Hyp = 15 :) that seems reallly good .. :P
x = 15 there you go
what can you double and then add -6 to get -16
Answer:
- 5
Step-by-step explanation:
let the number be n then double is 2n , so
2n + (- 6) = - 16
2n - 6 = - 16 ( add 6 to both sides )
2n = - 10 ( divide both sides by 2 )
n = - 5
The number is - 5

A basketball shaped like a sphere has a diameter of 8 inches. Which measurement is
to the volume of the basketball in cubic inches?
Answer:
268
Step-by-step explanation:
The volume formula for a sphere is: V= [tex]\frac{4}{3}\pi r^{3}[/tex]
We also know that [tex]\pi[/tex] is approximately 3.14.
You have to know these in order to solve the question..
Since we also know the diameter is 8 we can also find the radius (r) ,which is half of the diamater so 4.
Now all we need to do it plug in the numbers.
V= [tex]\frac{4}{3}[/tex](3.14)[tex]4^{3}[/tex]
Now solve for the equation.
V=267.94...
So rounded that is 268.
