(0,0) is the origin of a coordinate plane.
Answer:
none of these numbers are not right the real answer is 1088
Step-by-step explanation:
17 x 4 = 16
16 x 4 = 272
272 x 4 = 1088
The numbers do not matter. There are 3 outcomes for the first spinner and 6 outcomes for the second. 6x3 is 18. For each of the 3 outcomes for the first spinner there are 6 for the second.

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 =![32^{\circ}](https://tex.z-dn.net/?f=32%5E%7B%5Ccirc%7D)
The angle between sides AB and BC=![90+32=122^{\circ}](https://tex.z-dn.net/?f=90%2B32%3D122%5E%7B%5Ccirc%7D)
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
![c=\sqrt{a^2+b^2-2ab cos\theta}](https://tex.z-dn.net/?f=c%3D%5Csqrt%7Ba%5E2%2Bb%5E2-2ab%20cos%5Ctheta%7D)
Substitute the values in the given formula we get
![x=\sqrt{(135)^2+(55)^2-2(135)(55)cos 122}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B%28135%29%5E2%2B%2855%29%5E2-2%28135%29%2855%29cos%20122%7D)
![x=170.64 ft](https://tex.z-dn.net/?f=x%3D170.64%20ft)
Hence, the length of wire needed=171 foot
