Answer:
x = 3.6, the measure of the largest angle is 86.4
Step-by-step explanation:
15x + 24x + 21x = 180
50x = 180
180/50 = 3.6
x = 3.6
-------------------------
24x = 24(3.6)
24 * 3.6
86.4
the coordinates of 3 points are a(-1, -6), b(3, -12) and c(k, 6). Find the value of k if a, b and c are collinear.
Plz answer quickly and step by step.
Answer:
The value of [tex]k[/tex] is -9.
Step-by-step explanation:
If [tex]A(x,y) = (-1,-6)[/tex], [tex]B(x,y) =(3, -12)[/tex] and [tex]C(x,y) = (k,6)[/tex], then [tex]\overrightarrow{BC} = \alpha\cdot \overrightarrow{BA}[/tex]. By vectors sum, we find each vector below:
[tex]\overrightarrow{BA} = A(x,y)-B(x,y)[/tex] (1)
[tex]\overrightarrow{BA} = (-1,-6)-(3,-12)[/tex]
[tex]\overrightarrow{BA} = (-4, 6)[/tex]
[tex]\overrightarrow{BC} = C(x,y)-B(x,y)[/tex] (2)
[tex]\overrightarrow{BC} = (k,6)-(3,-12)[/tex]
[tex]\overrightarrow{BC} = (k-3, 18)[/tex]
By substituting in the equation defined at the begining of this answer:
[tex](k-3, 18) =\alpha\cdot (-4, 6)[/tex]
[tex](k-3, 18) = (-4\cdot \alpha, 6\cdot \alpha)[/tex] (3)
The value of [tex]\alpha[/tex] is:
[tex]6\cdot \alpha = 18[/tex] (3a)
[tex]\alpha = 3[/tex]
If we know that [tex]\alpha = 3[/tex], then the value of [tex]k[/tex] is:
[tex]k-3 = -4\cdot \alpha[/tex]
[tex]k = 3-4\cdot \alpha[/tex]
[tex]k = 3-4\cdot (3)[/tex]
[tex]k = 3-12[/tex]
[tex]k = -9[/tex]
Then, the value of [tex]k[/tex] is -9.

Given: Parallelogram QRST where QR = 6X - 5
and RS = 4x + 13. What is the length of QT?
The length of QT should be considered when the Parallelogram QRST where QR = 6X - 5 is to be [tex]x=-13/3[/tex].
Calculation of the length of QT:SInce
Parallelogram QRST where QR = 6X - 5 and RS = 4x + 13
So here we can write like
-3x = 13
x = [tex]-13 /3[/tex]
hence, The length of QT should be considered as the [tex]x=-13/3[/tex].

r = 4 in., θ = 11 rad; find s
Answer:
The arc length s = 44 inches
Step-by-step explanation:
We are given:
r = 4 in
Ф = 11 radians
We need to find s
The formula used is: [tex]s=r\theta[/tex]
where s represents arc length, r is radius and Ф is angle in radians
Putting values and finding s
[tex]s=r\theta[/tex]
Put r = 4 and Ф = 11
[tex]s=4\times 11\\s=44[/tex]
So, the arc length s = 44 inches
In the parallelogram shown, AE = t + 2, CE = 3t − 14, and DE = 2t + 8. Parallelogram A B C D is shown. Diagonals are drawn from point A to point C and from point D to point B and intersect at point E. What is the length of line segment DB? 20 units 24 units 48 units 68 units
Answer:
48 units
Step-by-step explanation:
A parallelogram is a polygon with four sides. Opposite sides and opposite angles of a parallelogram are congruent.
The diagonals of a parallelogram bisect each other.
In parallelogram ABCD, AC and DB are the diagonals. Since the diagonals meet at E, hence:
AE = CE and DE = BE (diagonals of a parallelogram bisect each other).
Since AE = CE, hence:
t + 2 = 3t - 14
3t - t = 2 + 14
2t = 16
t = 8 units
Therefore DE = 2t + 8 = 2(8) + 8 = 24 units
DE = BE = 24 units
But DB = DE + BE
DB = 24 + 24
DB = 48 units
Answer:
The answer is 48 units

John buys two types of tree saplings. One starts out at 40 cm and will grow 10 cm every three months. The other sapling starts at 20 cm and will grow 10 cm every two months. After how many months will they be the same height, and how tall will they be? solve for y and x
Answer:
They will at the same height of 80cm at 12 months.
Step-by-step explanation:
Sapling A:
y = 10/3x + 40
Sapling B:
y = 5x + 20
Set the equations to equal each other.
10/3x + 40 = 5x + 20
10/3x - 5x = 20 - 40
10x - 15x = 60 - 120
-5x = -60
x = 12
Sub x = 12 into one of the two equations (It doesn't matter which one you choose)
y = 5(12) + 20
y = 80

Given that :
Height of father's eye above the flat ground :
Kindly check attached picture for diagram:
To obtain the value of h ; we can use Pythagoras rule ;
Tan θ = opposite / Adjacent
Tan 48 = h / 15
15 tan 48 = h
37.126302 = h
h = 37.
Hence, height of father's above the flat ground :
h + 32 = 37 + 32= 69 inches
