Step-by-step explanation:
A vertical flagpole, AB, has a height of 46m. The points B, C and D lie on level ground, and BCD is a straight line. Point C is 21 m from the base of the flagpole. The angle of elevation of the top of the flagpole from point D is 58
How far apart are points C and D?
Answer:
20 on c and 90 on d cause noth are kinda the same but different at the same time.

Answer:
Step-by-step explanation:
oh law of sines soo sin(A) / a = Sin(B) / b
2a)
here DE = side f then let's find that side with law of sines and plug side f in as 'a' in law of sines , so
Sin(28) / a = Sin(54) / 31 ( where a = f = DE )
can you do the algebra here Emily? or do you want me to show that?
Sin(28) *31 / Sin(54) = a
17.989 =a
18.0 =a (rounded to nearest 10th)
DE = 18.0 m
2b)
find RT where RT = side a
since they give use 2 of the other sides of the triangle we can quickly figure out the S angle. 180 = 71+62+S so S = 47° ( I'm going kinda fast b/c I don't know how much time you have :? )
then Sin(A) /a = Sin(B) / b
Sin(47) / a = Sin(62) / 29
Sin(47) *29 / Sin(62) = a
24.020 = a
RT = 24.0 meters ( rounded to nearest 10th )
2c)
they want us to find ∠X with law of sines soo
I'll just use the letter they give us for variables
Sin(X) / x = Sin(Y ) / y
Sin(X) = x* Sin(y) / y
X = arcSin [ 14 * Sin(108) / 34 ]
X = arcSin [ 0.3916115]
X = 23.0548°
X= 23° ( rounded to nearest degree )
2d)
they ask us to find ∠E
I'll , again, use the letter they give us for variables
Sin(E) / e = Sin( F ) / f
Sin(E) / 18 = Sin(78) / 30
E = arcSin[ 18 * Sin(78) / 30 ]
E = arcSin [ 0.5868856 ]
E = 35.936 °
E = 36 ° ( rounded to nearest degree )

Answer:
C
Step-by-step explanation:
it is a right triangle and the hypotanueses are congruent but we need a leg also to be congruent before we can say they are congruent so the answer is C.
If my answer helps please mark as brainliest.
Answer:
Step-by-step explanation:
I don't think there's enough information to do it.
HL is about the closest one, but the congruency marks only show that the hypotenuse is marked. You need something else.
AAS SAS ASA are all eliminated because no angle besides the right angle is given. The right angle is fine if the two sides making it up were marked. They are not.

2x + 3y = 13
x - 3y = 2
Answer:
use the 2nd equation to find that x=3y+2 and now plug it into the first equation to get 2(3y+2)+3y=13 distribute to get 6y+4+3y=13, reorganize the equation by adding common integers to become 9y+4=13, Subtract 4 from both sides to get 9y=13-4, or 9y=9, so y=1, plug that into the equation for x to get x=3+2, so y=1 and x=5

Choose the question that has only one possible answer.
A. How tall are you?
B. What are the lengths of the lizards in your backyard?
C. What are the heights of the people in your class
Answer:
A. How tall are you?
Step-by-step explanation:
The response given to a questions will usually depend on the type of question asked. We have the open ended and the close ended. depending on whether the question can be answered by a yes or no alternative.
The question how tall are you? Simply requires a phrase answer with the height of the person being asked. Such as 6 feets, 12 feets, etc.
The question, length of lizards in backyard and the height of students in class requires a range of values to express the height of the lizards and students.
The chords intersect at point U.
A circle is shown. Chords R T and Q S intersect at point U. The length of R U is 12 centimeters, the length of U T is 4 centimeters, the length of U S is y centimeters, and the length of Q U is 8 centimeters.
What is the value of y?
2
4
6
8
Answer:
Its b)6
Step-by-step explanation:
I just did it on edge and got it correct
The value of y is 6 centimeters.
Given that,
The length of RU = 12 centimeters
The length of UT = 4 centimeters
The length of QU = 8 centimeters.
The length of US = y centimeters
What is the intersecting chords theorem?The intersecting chords theorem states that, the product of one whole chords segment and its external segment is equal to the product of the other whole chords segment and its external segment when two chords cross at an exterior point.
According to the intersecting chords theorem,
US x QU = RU x UT
Substitute the values in above formula,
y x 8 = 12 x 4
y = 48/8
y = 6 centimeters,
Hence, the value of y is 6 centimeters.

The Answer is A
Step-by-step explanation:
Trust me I just did the Assignment.
The correct function which has a constant additive rate of change of -1/4 is shown in figure 1.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable.
Given that;
To find the correct function which has a constant additive rate of change of -1/4.
Now, From figure 1;
Two points are (2,1) and (- 2, 2).
Hence, We get;
Rate of change = (2 - 1) / (- 2 - 2)
= - 1/4
Thus, The correct function which has a constant additive rate of change of -1/4 is shown in figure 1.

Answer
A: 23
B: 83
C: 183
D: 90
Answer:
Option B
83°
Step-by-step explanation:
Since,
To prove it as a kite then according it,
Ac should be a perpendicular bisector of BD
Hence,
<APB = 90°
Also given,
<APB = (x + 7)°
Therefore, by the problem,
=> x + 7 = 90
=> x = 90 - 7
=> x = 83°(Ans)
