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
Answer:
Can't wait to learn geometry (shapes math) in a year or 1/2. This looks very interesting and mind blowing.
Step-by-step explanation:
Answer:
x = 8 ; x = -3
Step-by-step explanation:
Sum = -5
Product = - 24
Factors = 3 , (-8)
x² - 5x - 24 = 0
x² - 8x + 3x - 3 * 8 = 0
x(x - 8) + 3(x - 8)= 0
(x - 8)(x + 3) = 0
x - 8 = 0 ; x + 3 = 0
x = 8 ; x = -3
Get all the x terms on one side, and the w on the other.
Add 37x on both sides to get 56x+rx=w.
Use the distributive property backwards to get x(56+r)=w.
Divide by 56+r on both sides to get x=w/(56+r)
