The complete question in the attached figure
we know that
[scale]=1 in / 30 ft
scale=[measure in the drawing]/[measure in the actual]
[measure in the actual]=[measure in the drawing]/[scale]
so
[measure in the drawing]=1.25 in
scale=1/30
then
[measure in the actual]=[1.25]/[1/30]------> 1.25*30-----> 37.5 ft
the answer is<span>
the Actual height is 37.5 ft</span>
In a 30 60 90 triangle, the short side = one half the hypotenuse = 4.5
The middle side = short side * sq root of 3
So, the middle side = 4.5 * sq root of 3 (

Perimeter = 4.5 + 7.7942 + 9
Perimeter =

Let's write 3:5 = 3k:5k. Then using perimeter formula, we can write that

and k=5 cm. The sides are 15 cm and 25 cm. The area is
Answer:
the value of x is x = 130 degrees
3600 meters 60 seconds would be 1440 traveled
and 1440 + 1440 + 720= <u>3600</u>
Hope this helps :)
