Answer:
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
The width of the room is 30 meters.
If two beams will be making an angle, they will half the width.
There will be a right triangle made, so using SOH CAH TOA,


taking cos inverse
x = 
x = 28.07° : Answer
Hope it will help :)
The correct answer is D.
The symbol you are looking at is sigma, which means sum of all. Because the number on the bottom is 1 and the top is 6, these are the start and end numbers for our n value. Therefore, it means to add together all of the values of your expression (n -3), for all of the values with n equaling between 1 and 6. So let's plug in all of the numbers for n they ask for and see what we have.
1
1 - 3 = -2
2
2 - 3 = -1
3
3 - 3 = 0
4
4 - 3 = 1
5
5 - 3 = 2
6
6 - 3 = 3
Now, when we add all of these numbers up, we look for the answer.
-2 + -1 + 0 + 1 + 2 + 3 = 3
This is the answer we see in D
Answer:
15 5/8 in³ (=15.625 in³)
Step-by-step explanation:
recall
volume of cube = length ³
given length = 2 1/2 = 5/2 inches
volume of cube,
= (5/2) ³
= 5³ / 2³
= 125 / 8
= 15 5/8 in³

Answer:
8.4
Step-by-step explanation:
In similar triangles, corresponding measures are proportional.
FG/FJ = ST/SH
FG = FJ×ST/SH = 7×6/5 . . . . solve for FG, put in given values
FG = 8.4
