Answer:
D. cannot be determined
Step-by-step explanation:
that is kind of a trick question.
right based on the given information none of the 3 methods can be applied.
we don't have all 3 sides for SSS
we don't have 2 angles for AA
and we don't have 2 sides with their included angle for SAS.
but it can still be determined (they ARE similar), as this is a special case of SSA, where it is clear that the corresponding congruent angles are located at the same position relatively to the corresponding similar lines.
you can discuss this with your teacher, if you are interested.
AND - we can easily determine any of the other missing pieces (side and angles). these missing pieces then will correspond exactly to their counterparts in the other triangle (the 2 angles in ABC are equal to the 2 angles in DEF, the missing sides file the same scaling factor as the other known sides). and then any of the 3 methods can be applied.
so, this is actually tricky ...

Answer:
46degrees
Step-by-step explanation:
From the question, we are told that both triangles are similar, hence;
<E = <S
<D = <R
<F = <T
From triangle DEF
<D + <F + <E = 180
Since <D = <F = 67
67 + 67 + <E = 180
134 + <E = 180
<E = 180 - 134
<E = 46degrees
Since <E = <S, hence the measure of <S is 46degrees

(Show full work please) Carter spots an airplane on radar that is currently approaching in a straight line, and
that will fly directly overhead. The plane maintains a constant altitude of 7250 feet.
Carter initially measures an angle of elevation of 16 to the plane at point A. At some
later time, he measures an angle of elevation of 26° to the plane at point B. Find the
distance the plane traveled from point A to point B. Round your answer to the
nearest foot if necessary
Answers
Consult the attached diagram.
In the larger triangle,
tan(16°) = (7250 ft) / (x + y)
and in the smaller triangle,
tan(26°) = (7250 ft) / y
You want to solve for x.
From the first equation (I'm ignoring units from here on, all distances are measured in ft), you have
(x + y) tan(16°) = 7250
x tan(16°) + y tan(16°) = 7250
x tan(16°) = 7250 - y tan(16°)
x = 7250 cot(16°) - y
From the second equation,
y = 7250 cot(26°)
Solving for x gives
x = 7250 cot(16°) - 7250 cot(26°)
x = 7250 (cot(16°) - cot(26°))
x ≈ 10,433 ft
The distance the plane traveled from point A to point B is 10,433 ft.
We have given that,
Carter spots an airplane on the radar that is currently approaching in a straight line, and that will fly directly overhead.
The plane maintains a constant altitude of 7250 feet.
In the larger triangle,tan(16°) = (7250 ft) / (x + y)and in the smaller triangle,
What is the tan ratio?[tex]tan(\ theta)=\frac{\\opposite \side }{hypotenouse}[/tex]tan(26°) = (7250 ft) / y
we have to solve for x.
From the first equation (I'm ignoring units from here on, all distances are measured in ft),
you have
(x + y) tan(16°) = 7250
x tan(16°) + y tan(16°) = 7250
x tan(16°) = 7250 - y tan(16°)
x = 7250 cot(16°) - y
From the second equation,
y = 7250 cot(26°)
Solving for x gives
x = 7250 cot(16°) - 7250 cot(26°)
x = 7250 (cot(16°) - cot(26°))x ≈ 10,433 ft
Therefore the distance the plane traveled from point A to point B is 10,433 ft.

The problem states that Brian can travel ‘27.5’ miles per gallon, and his tank can only hold ‘15.45’ gallons of fuel.
To find the miles he can travel, all you have to do is multiply the miles he can travel per gallon (27.5) by the gallons he has in the tank (15.45).
This gives you the answer of 424.875 miles.
Answer:
27.5 miles per gallon
1 full tank = 15.45 gallons
27.5 x 15.45 = 424.875 miles
rounded to the nearest 100th: 424.88 miles
nearest 10th: 424.9 miles
nearest whole #: 425 miles

According to the Question,
Given That, Let V be the set of all 3x3 matrices with Real number entries, with the usual definitions of scalar multiplication and vector addition. Consider whether V is a vector space over C.For V is a vector space over C and V is Set of 3x3 Matrices with Real entries.Then, For any u,w ∈ V ⇒ u+w ∈ V
And u∈V and z∈C ⇒ z u ∈ V
So, If we take any z= i ∈ C
and V be any 3x3 matrices with Real entrices.then, z,v ∉ V ∴z,v Has Complex entries
So, the Scalar Closure axiom is not satisfied
Hence, V is not a Vector Space of C
Any u,w ∈ W ⇒ u+w ∈ V
So, The Additive Closure axiom is satisfied.

✔️Coordinates of vertices ABC:

✔️AC = |2 - (-1)| = 3 units
AB = |2 - 6| = 4 units
2. Distance formula => [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Distance between B(6, 2) and C(2, -1):
[tex] BC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Where,
[tex] B(6, 2) = (x_1, y_1) [/tex]
[tex] C(2, -1) = (x_2, y_2) [/tex]
[tex] BC = \sqrt{(2 - 6)^2 + (-1 - 2)^2} [/tex]

[tex] BC = \sqrt{16 + 9} = \sqrt{25} [/tex]
[tex] BC = 5 units [/tex]
Answer:
The person above me has the correct answer and solves it in the correct way.
Step-by-step explanation:
This is what I used as my answer though.
Distance Formula: d = √(x2-x1)^2 + (y2-y1)^2
BC = √(x2-x1)^2 + (y2-y1)^2
B = (6,2)
C = (2,-1)
BC = √(2-6)^2 + (-1-2)^2
BC = √(-4)^2 + (-3)^2
BC = √16+9
BC = √25
BC = 5
