Answer:
The length of the wire is 76.19 m.
Step-by-step explanation:
It is given that a guy wire is attached to the top of a radio antenna and to a point on horizontal ground that 40 m from the base of the antenna.
It means base of the right angled triangle is 40 m.
The wire makes an angle of 58deg 20min with the ground.
1 degree = 60 min
Using this conversion convert the given angle in degree.
In a right angled triangle
Therefore the length of the wire is 76.19 m.

F)
Step-by-step explanation:
C)
One is given the following equation
In order to simplify fractions, one must convert the fractions to a common denominator. The common denominator is the least common multiple between the given denominators. Please note that the denominator is the number under the fraction bar of a fraction. In this case, the least common multiple of the denominators is (). Multiply the numerator and denominator of each fraction by the respective value in order to convert the fraction's denominator to the least common multiple,
Simplify,
E)
In this case, one is given the problem that is as follows:
Use a similar strategy to solve this problem as used in part (c). Please note that in this case, the least common multiple of the two denominators is the product of the two denominators. In other words, the following value: ()
Simplify,
F)
The final problem one is given is the following:
For this problem, one can use the same strategy to solve it as used in parts (c) and (e). The least common multiple of the two denominators is (). Multiply the first fraction by a certain value to attain this denomaintor,
Simplify,
