A 500-foot weathertower used to measure wind speed has a guy wire attached to it 200 feet above the ground. The angle between the wire and the vertical tower is 47 degrees. Approximate the length of the guy wire to the nearest foot.
Answers
The length of the guy wire is 273.5 feet.
Trigonometric ratio show the relationship between the sides and angles of a right angled triangle.
Let d represent the length of the guy wire.
Using trigonometric ratios:
The length of the guy wire is 273.5 feet.

Answer: 293 feet
==========================================
Explanation:
See the attached image below. The information that the tower is 500 ft is never used. Focus solely on triangle ABD (ignore point C).
AB = 200
AD = x = unknown
angle ABD = angle B = 47 degrees
Use the cosine rule to help find x
---------
cos(angle) = adjacent/hypotenuse
cos(B) = AB/BD
cos(47) = 200/x
x*cos(47) = 200
x = 200/cos(47)
x = 293.255837127926
Rounding to the nearest foot, we get 293 feet as the answer.

Answer:
D.There is no error.
Step-by-step explanation:
We are given that Jacob is showing his steps to solve the expression
We have to find the error in Jacob steps in which he makes error
Jacob writes his first step
Step:1
Jacob's first step is true.
We know that if we changes divide sign of term into multiply then the the term which is write on right side of divide sign reciprocal. Therefore,
Step:2
Hence, Jacob's second step is right.
Now , we multiply -27.8 with 7 then we get
Step:3
Hence, Jacob's third step is also right.
Therefore, Jacob makes no error in his steps.
Hence, Option D is true.

(A) 4 mph
(B) 5 mph
(C) 6 mph
(D) 30 mph
Answers
Answer:
(C) 6 mph
Step-by-step explanation:
Given,
The time taken by Tobin = 30 minutes,
While, the time taken by her opponent = 45 minutes,
So, the ratio of the time taken by tobin and her opponent = 30 : 45
Thus, the ratio of speed of tobin and her opponent =
= 45 : 30
= 3 : 2
Suppose speed of tobin = 3x and speed of opponent = 2x
Where, x is positive real number,
Difference in speed = 3x - 2x = x
According to the question,
x = 2 miles per hour,
Hence, the speed of Tobin = 3x = 6 miles per hour.
Option (C) is correct
d = ( x + 2) *30 Tobin
x * 45 = ( x + 2) *30
x* 15 = 60
x = 4
x + 2 = 6 mph
