The answer is you need to post a pic in order to give help
Imagine the shadow and the building height forms a right angle triangle;
We know the height and the shadow make up the "legs" of the triangle,
a²+b²=c²
(750)²+(111)²=c²
562500+12321=c²
574821=c²
c=√574821
c=758.169 ≈ 758.2 ft
Hope I helped :)
To solve this, you have to do the following.
1/12 X 20
You can lower the values of 12 and 20 by dividing with 2
Now it will be
1/6 X 10
Again you can divide it by 2
=>1/3X5
As you can no longer divide you multiply 5 times 1
The final Answer is
5/3
Answer:
proportional: 1, 3,5,6,8,10
non: 2,4,7,9,11,12
