Answer:
[tex]<D=95[/tex]
Step-by-step explanation:
The opposite angles in a quadrilateral theorem states that when a quadrilateral is inscribed in a circle, the angles that are opposite each other are supplementary, their degree measures add up to 180 degrees. One can apply this here by using the sum of (<C) and (<A) to find the measure of the parameter (z). Then one can substitute in the value of (z) to find the measure of (<B). Finally, one can use the opposite angles in a quadrilateral theorem to find the measure of angle (<D) by using the sum of (<B) and (D).
Use the opposite angles in an inscribed quadrialteral theorem,
<A + <C = 180
Substitute,
14x - 7 + 8z = 180
Simplify,
22z - 7 = 180
Inverse operations,
22z = 187
z = [tex]\frac{187}{22}[/tex]
Simplify,
z = [tex]\frac{17}{2}[/tex]
Now substitute the value of (z) into the expression given for the measure of angle (<B)
<B = 10z
<B = 10([tex]\frac{17}{2}[/tex])
Simplify,
<B = 85
Use the opposite angles in an inscribed quadrilateral theorem to find the measure of (<D)
<B + <D = 180
Substitute,
85 + <D = 180
Inverse operations,
<D = 95

Find the midpoint
(1,-8) (-7,0)
Answer:
(-3, -4)
Step-by-step explanation:
Handy fact: the average of two numbers is exactly halfway between them.
To find the midpoint, average the x-coordinates; average the y-coordinates.
(1 + -7)/2 = -6/2 = -3
(-8 + 0)/2 = -8/2 = -4
The midpoint is (-3, -4).
Order these numbers from least to greatest.

Answer:

Step-by-step explanation:
The surface area of the given prism consists of the following parts;
1) The area of the top and bottom right triangles, A₁, and A₂, which are given as follows;
A₁ = A₂ = (1/2) × 5 × 12 = 30
2) The area of the left rectangle, A₃ = 5 × 8 = 40
3) The area of the rear rectangle, A₄ = 13 × 8 = 104
4) The area of the front rectangle, A₅ = 12 × 8 = 96
∴ A = A₁ + A₂ + A₃ + A₄ + A₅
A = 30 + 40 + 104 + 96 + 30 = 300
Jim B 65 + 65 + 104 + 96 + 40 = 370
The surface area of the triangular prism, A = 300 cm²
Jim-Bob's calculation contains two errors
1) 65 + 65 + 104 + 96 + 40 = 370 ≠ 270
2) The area surface area of the triangular prism = 300 cm² not 270 cm²
and therefore, disagree with his calculation.
A map using a scale of 1 inch:5 miles shows a section of land with an area of 3.2 inches what is the actual area of the section of the land
Answer:
16 miles
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
Actual area = 3.2 x 5 = 16 miles
The perimeter of a triangular park is (16x + 3) feet. Two of the sides are 5x - 1 and 2x + 5. What is the missing length?
Answer:
9x - 1
Step-by-step explanation:
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
Area of a triangle = 1/2 x base x height
the perimeter of a triangle = sum of the side lengths
missing length = perimeter - sum of the two sides
sum of the two sides = (5x -1) + (2x + 5) = 7x + 4
missing length = 16x + 3 - (7x + 4) = 9x-1
In Marvel comics, T'Challa (aka The Black Panther) as the king of Wakanda
is estimated to be worth 90 trillion (9 x 1013) dollars. Tony Stark (aka Iron
Man) is only worth about 30 billion (3 x 1010) dollars. If Tony Stark could
somehow add a 10% increase in his wealth to his current worth each year
($30 billion, $63 billion, $99.3 billion, etc.), how many years would it take
to reach T'Challa? Round your answer to the nearest year.
If Tony Stark could somehow add a 10% increase in his wealth to his current worth each year then the number of years will be 84 to reach T'Challa.
What is an exponent?Exponential notation is a type of mathematical shorthand that allows us to express complex statements in a more concise manner. The basis of an exponent is a quantity or letter. It denotes that the base will rise to a specific level of strength. The base is X, and the power is n.
In Marvel comics, T'Challa (aka The Black Panther) as the king of Wakanda is estimated to be worth 90 trillion dollars.
Tony Stark (aka Iron Man) is only worth about 30 billion dollars.
If Tony Stark could somehow add a 10% increase in his wealth to his current worth each year.
Let t be a number of the years.
Then the equation is given as
[tex]\rm 9 \times 10^{13} = 3 \times 10^{10} \times (1.10)^t[/tex]
Then the value of t will be
[tex]\rm 3000= (1.10)^t\\[/tex]
Taking log both sides, we have
t (ln 1.1) = ln 3000
t = 84

Applying the Pythagorean theorem, solve this triangle.
Answer:
The length of the hypotenuse is the square root of 169, which in turn is 13.
Step-by-step explanation:
Here we have a right triangle with leg lengths 12 m and 5 m. Because this is a right triangle, we can apply the Pythagorean Theorem to find the length of the hypotenuse.
The Theorem states that a^2 + b^2 = c^2. In this particular case,
(12 m)^2 + (5 m)^2 = c^2
which in turn becomes:
144 + 25 = 169. The length of the hypotenuse is the square root of 169, which in turn is 13.

[tex]d=60ft[/tex]
Step-by-step explanation:
From the question we are told that:
Height [tex]h= 30ft[/tex]
Angle [tex]\theta=30 \textdegree[/tex]
Generally the equation for Distance traveled is mathematically given by
Since
Distance traveled forms the hypotenuse of a right angle triangle
