Answer:
Adjacent leg (In relation to the angle that is measure 22 degrees)= 70*Cosine 22 or 64.9; Opposite leg (In relation to the angle that is measure 22 degrees)=70* Sin 22 or 26.22
Step-by-step explanation:
The other angle measure is 90-22 or 68.
To find the length of the adjacent leg (a) use cosine. Remember cosine is Adjacent leg over hypotenuse.
Cosine 22= a/70- Multiply by 70
70* Cosine 22=a or about 64.9
To find the length of the opposite leg (o) use sine. Remember sine is Opposite leg over hypotenuse
Sine 22= o/70
70*Sine 22=o
o= about 26.22
La ecuación de la recta que pasa por los puntos (2,-1) y (1,-5) es:
y= 4x+9
y= 4x-9
y= x-9
ninguna de las anteriores
Given:
A line passes through the points (2,-1) and (1,-5).
To find:
The equation of the line.
Solution:
If a line passes through the two points, then the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The line passes through the points (2,-1) and (1,-5). So, the equation of the line is
[tex]y-(-1)=\dfrac{-5-(-1)}{1-2}(x-2)[/tex]
[tex]y+1=\dfrac{-5+1}{-1}(x-2)[/tex]
[tex]y+1=\dfrac{-4}{-1}(x-2)[/tex]
[tex]y+1=4(x-2)[/tex]
Using distributive property, we get
[tex]y+1=4(x)+4(-2)[/tex]
[tex]y+1=4x-8[/tex]
Subtract 1 from both sides.
[tex]y+1-1=4x-8-1[/tex]
[tex]y=4x-9[/tex]
Therefore, the correct option is B.
solve the equation=3x =15
3x = 15
x = 15/3
x = 5
Answer:
x = 5
Step-by-step explanation:
3x = 15
x = 15/3
x = 5

Please help me with finding the length of AC. I’ll make this 20 points since it’s kinda long. Please don’t guess my grades depends on it
Since the triangle is a right angled, to find one side we should use the pythagoras theorem.
The longed side of the triangle is called the hypotenuse.
In equation form: x² + y² = z²
Therefore: 12² + x² = 13²
114+x²= 169
x²= 169-114
x²= 55
x = 7.41
Therefore the length of AC = 7.41
PLEASE HELP WHAT IS THE ANSWER SHOW WORK PLEASE !!!
Answer:
d = 6.1m
n = 7km
Step-by-step explanation:
To find the variables, use tan
⇒ tan = [tex]\frac{opposite}{adjacent}[/tex]
finding d:
⇒tan 63 = [tex]\frac{d}{3.1}[/tex]
tan of 63 is 1.963
⇒ 1.963 = [tex]\frac{d}{3.1}[/tex]
multiply 3.1 on both sides
⇒ 1.963 x 3.1 = [tex]\frac{d}{3.1}[/tex] x 3.1
⇒ 6.0853 = d
round to the nearest tenth:
⇒ 6.0853 = 6.1
finding n:
⇒ tan 45 = [tex]\frac{7}{n}[/tex]
tan of 45 is 1
⇒ 1 = [tex]\frac{7}{n}[/tex]
multiply 7 on both sides:
⇒ 1 x 7 = [tex]\frac{7}{n}[/tex] x 7
7 = n
Answer:
D = 1.4, N =
Step-by-step explanation:
To get D you need to find the cosine of 63 degrees
Cosine(63) = D / 3.1
Multiply by 3.1 to isolate D :
3.1Cosine(63) = D
Put it into a calculator and you'll get 1.4.
Also, it's a 45-45-90 triangle so the 2 legs will be equal to each other.
Proof: To get N put you have to do the tangent of 45 degrees
Tan(45) = 7 / N
Now you can't to do this you have to multiply the both sides by N
N(tan(45)) = 7
Then divide both sides by (tan(45))
N = 7 / (tan(45)
Put it into the calculator and you'll get

12x-17 = 6x+7 solve for x
-8b+1 = -5(b + 4) solve for b
350+10(n-7) = 630+2(n-15) solve for n
thank you
Answer:
x = 4
b = 7
n = 40
I hope this helps!!!
Step-by-step explanation:
1) 12x-17 = 6x+7
+17 +17
*do this because you want to get all of the variables to one side and all of the constants to one side*
12x = 6x + 24
-6x -6x
6x = 24
*divide by 6 to get x alone, so you 24/6 = 4*
x = 4
2) -8b+1 = -5(b+4)
*must multiply -5 by everything in the parenthesises*
-8b+1 = -5b-20
-1 -1
-8b= -5b-21
+5b +5b
-3b = -21
b = 7
3) 350+10(n-7) = 630+2(n-15)
350+10n-70 = 630+2n-30
*combine like terms on both sides of the equation*
280+10n = 600+2n
-280 -280
10n = 320+2n
-2n -2n
8n = 320
n = 40

A tree struck by lightning broke at a point 12 feet above the ground. What was the height of the tree to the nearest tenth of a foot., 12 squared + 39 squared = ??
Answer:
52.8 feets
Step-by-step explanation:
From the diagram :
The height of tree woulb be :
Height above the ground (at breakpoint) + hypotenus
Hypotenus, h cab be obtained using Pythagoras rule :
h² = opp² + adj²
h² = 39² + 12²
h² = 1665
h = sqrt(1665)
h = 40.804 feets
Height of tree to the nearest tenth ;
40.804 feets + 12 feets
= 52.804 feets
= 52.8 feets

A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 12 cm, and the base has a
radius of 3.5 cm. How much water is needed to fill 50 cups?
Use 3.14 for pi and do not round your answer.
Answer: 7693cm
Step-by-step explanation:
The volume of a cone is given as:
= 1/3πr²h
where π = 3.14
radius = 3.5cm
height = 12
Volume = 1/3πr²h
= 1/3 × 3.14 × 3.5² × 12
= 153.86cm³
Therefore, the amount of water that is needed to fill 50 cups will be:
= 153.86 × 50
= 7693cm

Which angle is complementary to DFE? Pls answer
Answer:
<DFA
Step-by-step explanation:
When combined (<DFA and <DFE), they'll form 90 degrees which will make them complementary
Answer:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary. If you know one acute angle, you can calculate its complementary angle by subtracting 90 and the angle. When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
The complement of −135° is the angle that when added to −135° forms a right angle (90° ).
