Answer:
171 foot
Step-by-step explanation:
We are given that
Height of tower=135 ft
AC=55 ft
Let x be the length of shortest length of wire.
The angle of inclination of mountain with horizontal =
The angle between sides AB and BC=
Exterior angle is equal to sum interior angles of a triangle on the opposite sides .
We have to find the value of x.
We know that law of cosine

Substitute the values in the given formula we get


Hence, the length of wire needed=171 foot
The constant of proportionality k is given by y = kx.
In your equation, it would be r = km.
Can you now spot it?
Answer:
8 1/2
Step-by-step explanation:
16+25=41+25=66+25=91+25=116+25=131+25=156+25=181+25=201+25=226
so it takes 8 and a half hours
3/5(30x - 15) = 72
18x - 9 = 72 <==== this is one
3(6x - 3) = 72 <== this is one
18x = 81 <== this is one
x = 81/18
x = 4.5 <== this is one
