A man standing near a radio station antenna observes that the angle of elevation to the top of the antenna is 64 He then walks 68 feet further away and observes that the angle of elevation to the top of the antenna is 43 Find the height of the antenna to the nearest foot.
The height of the radio station antenna is approximately 116 feet to the nearest foot.
From the diagram in the attached image
[tex]h=\text{the height of the radio station antenna}\\x=\text{the distance from the foot of the radio station antenna to where the man stood at first}[/tex]
we now have the following relationships
[tex]tan64^\circ=\frac{h}{x}\\\\\implies x=\frac{h}{tan64^\circ}[/tex]
and
[tex]tan43^\circ=\frac{h}{68+x}\\\\\implies x=\frac{h}{tan43^\circ}-68[/tex]
we can equate the two relationships to eliminate [tex]x[/tex].
[tex]\frac{h}{tan64^\circ}=\frac{h}{tan43^\circ}-68[/tex]
solving for the height of the radio station antenna, [tex]h[/tex], we get
[tex]h=\frac{68\times tan43^\circ \times tan64^\circ}{tan64^\circ -tan43^\circ}\approx 116ft\text{ (to the nearest foot)}[/tex]

If OQ and RT are parallel lines and mZRSP = 55°, what is mZQPS?
Answer:
55 degrees
Step-by-step explanation:
Angles RSP and QPS are Alternate Interior Angles. Given that OQ and RT are parallel, alternate interior angles are always congruent, meaning they have the same measure.
So if angle RSP is 55 degrees and it is congruent to angle QPS, then angle QPS is 55 degrees.

What is the length of the line segment joining these points?
Enter your answer as a decimal in the box.
Answer:
9.2 units
Step-by-step explanation:
The length of the segment between the points is equal to the difference of their coordinates:
3.7 -(-5.5) = 3.7 +5.5 = 9.2 . . . units
Answer:

Answer:
GF ≈ 11.2HD ≈4.3∠HDE ≈68.8°Step-by-step explanation:
The relevant trig relations are ...
Tan = Opposite/Adjacent
Sin = Opposite/Hypotenuse
These tell us ...
tan(43°) = GH/DG
GH = DG·tan(43°) = (12 cm)·tan(43°) ≈ 11.2 cm
and ...
sin(HDE) = EH/ED = (11.2 cm)/(12 cm)
∠HDE = arcsin(11.2/12) ≈ 68.8°
The length HD can be found from ...
tan(68.8°) = HE/HD
HD = HE/tan(68.8°) = (11.2 cm)/tan(68.8°) ≈ 4.3 cm

d = √ ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2 Evaluate d if ( x 1 , y 1 ) = ( − 3 , 4 ) and ( x 2 , y 2 ) = ( − 2 , 4 ) .
Answer:
1
Step-by-step explanation:
let's substitute the numbers:
[tex]d=\sqrt{[-2-(-3)]^2+(4-4)^2}=\sqrt{(-2+3)^2-0^2}= \sqrt1= 1[/tex]
The value of d if [tex](x_1,y_1)=(-3,4)[/tex] and [tex](x_2,y_2)=(-2,4)[/tex] in [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] is 1.
DistanceThe distance between the two co-ordinates points can be evaluated by using the formula [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the coordinates of the endpoints.
How to evaluate the distance?The given coordinate points are [tex](x_1,y_1)=(-3,4)[/tex] and [tex](x_2,y_2)=(-2,4)[/tex].
Substitute the values of the known parameters in the formula [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] as-
[tex]d=\sqrt{(-2-(-3))^2+(4-4)^2}\\=\sqrt{(-2+3)^2}\\=1[/tex]
Hence, the value of d is 1.

Cody sold half of his comic books and then bought seventeen more. He now has 41. With how many did he begin?
Answer:
He begun with 48.
Step-by-step explanation:
48/2 = 24
24+17 = 41
Answer:
46
Step-by-step explanation:
I subtracted 17 from 41 and got 23 so if you add 23 by 23 half you get 46, so in turn Cody started out at 46.
