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.
Answer:
3.4
Step-by-step explanation:
5t+5/4-1=4t-3/5. cross multiply over the bracket
(5t+5)5=(4t-3)(4-1)
25t + 25 = -16t -4- 12 - 3
Combine the like terms
25t - 16t +4t = -4-12-3-25
13t = - 44
Divide both sides by 13
3.38
3.4 approximately

Step-by-step explanation:
Answer:
y = -1/2x - 7
Step-by-step explanation:
y2 - y1 / x2 - x1
-6 - (-5) / -2 - (-4)
-1 / 2
= -1/2
y = -1/2x + b
-5 = -1/2(-4) + b
-5 = 2 + b
-7 = b
