Answer:
75cm
Step-by-step explanation:
Well, I can't see a photo, so I'll have to assume that the description provides enough info.
10cm/2km = x/15km,
where x is the distance on the map (in centimeters) of a real-life distance of 15 kilometers.
10cm/2km = x/15km
10/2 = 5/1
This means we have to multiply 5 by 15 to find x.
x = 5 · 15
x = 75
Let's plug the new value back in...
10cm/2km = x/15km
10cm/2km = (75cm)/15km
<em>(Simplify each side to its simplest form)</em>
10cm/2km = 75cm/15km
5/1 = 5/1
It works! So x = 75cm.
Hope this helps! :)
By using trigonometric relations, we will see that the angle of elevation must be 55°.

How to find the angle of elevation?</h3>
We can see this as a right triangle, where one cathetus measures 1250ft (altitude) and the other cathetus measures 875ft.
The angle of elevation is the angle such that the adjacent cathetus is the one measuring 875ft.
Then we can use the relation:
tan(a) = (opposite cathetus)/(adjacent cathetus)
tan(a) = 1250ft/875ft
To find the angle of elevation, we can use the inverse tangent function:
a = Atan(1250ft/875ft) = 55°
The angle of elevation must be 55 degrees.

Answer:
120+100+120+120+x+x+10=720 (given)
470+2x=720
2x=720-470
x=250/2
x=125
