Answer:
Distance between two mountains= 12.5 km
Step-by-step explanation:
We are given a map scale of 1 inch=10 km
We have to find the distance between two mountains which are 1.25 inch apart in the map
1 inch=10 km
1.25 inch= 1.25×10 km
= 12.5 km
Hence, distance between two mountains is:
12.5 km
Cos°=B/H
=5/9
=0.5
=1/2
Cos60°=1/2
Therefore, x=60°
