Finn is looking into the position and range of 4G mobile towers in his local area. Finn learns that the range of the 4G mobile towers is 50 km, where there are no obstructions. (b) Finn looks at a map of 4G mobile towers in his area. There is one at Stormer Hill and another at Blackstone Edge. The top of these towers have heights of 251 m and 473 m respectively. Let point A be the top of the tower at Stormer Hill, point B be the point vertically beneath Blackstone Edge tower and on a level with the point A and let point C be the top of the tower at Blackstone Edge. A measurement of 4 cm on the map represents 1 km on the ground. (ii) What is the reduction scale factor? Give your answer in standard form. (iii) What is the actual distance between the tops of the two towers, the length AC? (iv) Calculate ZCAB, the angle which is the line of sight from the top of the mast at Stormer Hill to the top of the mast at Blackstone Edge.

(b) Finn looks at a map of 4G mobile towers in his area. There is one at
Stormer Hill and another at Blackstone Edge. The top of these towers
have heights of 251 m and 473 m respectively. Let point A be the top of
the tower at Stormer Hill, point B be the point vertically beneath
Blackstone Edge tower and on a level with the point A and let point C
be the top of the tower at Blackstone Edge. A measurement of 4 cm on
the map represents 1 km on the ground.
What is the reduction scale factor? Give your answer in standard
