Answer:
61
Step-by-step explanation:
Because all triangles's angles sum is always equal to 180, we can establish the equation, (9x - 31) + (7x - 2) + (4x + 33) = 180.
Simplifying, we get;
9x - 31 + 7x - 2 + 4x + 33 = 180
20x = 180
x = 9.
So, angle DCE = 7x - 2 = 7 * 9 - 2 = 63 - 2 = 61

[tex] \dfrac{-7600}{3} [/tex]
Step-by-step explanation:
The plane is descending, so the change in height is a negative change.
rate of descent = (change in height)/time
rate of descent = (new height - old height)/time
rate of descent = (7400 ft - 15000 ft)/(3 min)
rate of descent = (-7600 ft)/(3 min)

The cylinder has a volume of 12pi cubic inches and a diameter of 4 inches. Find the cylinders radius and height. The cylinders radius is______ inches and it’s height is_____ inches.
Answers
Answer:
The cylinder's radius is 2 inches and it’s height is 3 inches.Step-by-step explanation:
A diameter is two radiuses long, so the cylinder's radius is:
R = 4 in ÷ 2 = 2 in
The volume of cylinder is: V = πR²×H
Therefore:
12π = π×2²×H
12 = 4H
H = 3 in

Pulling out like terms
4.1 Pull out like factors :
x4 - 2x3 - 9x2 + 18x =
x • (x3 - 2x2 - 9x + 18)
Checking for a perfect cube :
4.2 x3 - 2x2 - 9x + 18 is not a perfect cube
Trying to factor by pulling out :
4.3 Factoring: x3 - 2x2 - 9x + 18
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -9x + 18
Group 2: x3 - 2x2
Pull out from each group separately :
Group 1: (x - 2) • (-9)
Group 2: (x - 2) • (x2)
-------------------
Add up the two groups :
(x - 2) • (x2 - 9)
Which is the desired factorization
Trying to factor as a Difference of Squares:
4.4 Factoring: x2 - 9
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 9 is the square of 3
Check : x2 is the square of x1
Factorization is : (x + 3) • (x - 3)
Final result :
x • (x + 3) • (x - 3) • (x - 2)

The side of the square garden is 30ft.
To find:
The length of the diagonal of the square garden.
Solution:
We know that, the length of the diagonal of a square is
[tex]d=a\sqrt{2}[/tex] ...(i)
Where, a is the the side of the square.
We have,
Side of the square garden = 30 ft.
Putting a=30 in (i), we get
[tex]d=30\sqrt{2}[/tex]
The measure of the diagonal path is [tex]30\sqrt{2}[/tex] ft.

In ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°. Find the length of f, to the nearest 10th of an inch.
Answers
In ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°. Find the length of f, to the nearest 10th of an inch.
=10.7
The length of f from the given triangle FGH is 10.7 inches.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² − 2bc·cosA.
Given that, in ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°.
Here, f² = 7.6² + 3.2² − 2×7.6×3.2×cos160°
f² = 57.76+10.24-48.64×(- 0.9396)
f² = 68+45.70
f² = 113.7
f = √113.7
f = 10.7 inches
Therefore, the length of f is 10.7 inches.
