Use cosine rule of triangle. let C be the dist between 2 transmitter then c(pow of 2)=70*70+130*130-2*70*130*cosine(117.4).Square root of c will give u the answer

The Law of Cosines
For a triangle with sides a,b, and c and the angle µ opposite the side c, one has
c2 = a2 + b2 - 2ab·cos(µ)
Use this law of cosine. Where C is the distance between the transmitters.

use scale of 1cm=40 miles.
draw a line of 130 miles(use the scale) as ur base line. At 1 end point draw an angleof 117.4. The line should be70 miles(use scale).
Form a triangle out of it. Find the length of the 3rd line u drew.

not positive yar but i THINK it is
.3044444444 times 147.6482306= about 50
