Answer:
b = 69/2 mm
Step-by-step explanation:
Let h: height of triangle
Let b: base length
Writing the height in terms of the base length: h = 2b + 5 mm
We equate that to the given height: 74 mm = h = 2b + 5 mm.
Solving this for b, we subtract 5 mm from both sides, obtaining
69 mm = 2b.
Then b = 69/2 mm

Answer options
A. Two cities that are 7.5 cm apart on the map are actually 50 km apart.
D. Two cities that are actually 66 km apart are 9.9 cm apart on the map.
Step-by-step explanation:
Step 1
Indicate the scale as shown;
3 cm : 20 km, meaning 3 cm on the map represents 20 km on the ground
A). what does 7.5 cm represent on the ground
Distance on ground=(7.5×20)/3=50 km
B). what does 4 cm represent on the ground
Distance on ground=(4×20)/3=26.67 km
C). what does 45 km on ground represent on the map
Distance on map=(45×3)/20=6.75 cm
D). what does 66 km on ground represent on the map
Distance on the map=(66×3)/20=9.9 cm
