An easy way (you must put the numbers in the correct side)
3 2 you cant subtract 5 from 2 so u carry one
-1 5 the 3
2 ¹3. it should look like this.Now u do 13-5=8
-1 5
2 ¹3. now u do 2-1=1
- 1 5
= 1 8
your final answer is 18.
8 yards is your answer
every 3 feet is one yard so just add it up
Answer:
Object will be at a distance of 358098.6 km from the source
Step-by-step explanation:
We have given angle = 0.0008 degree 
Radius is given = 2.50 km
Linear size of the object will be equal to diameter
So linear size = 2.5×2 = 5 km
We know that linear size 
So 
d = 358098.6 km
You can use the cosine rule for this - you might have to change some of the letters around for it to make sense though. Hope this helps!
