<u>The question is not complete. I have assumed you want to calculate the length of each piece.</u>
Answer:
<em>The shortest piece is 4 inches long</em>
<em>The longest piece is 8 inches long</em>
Step-by-step explanation:
Equations
One piece of tubing is two times the other.
Let's call
x=the shortest piece of tubing
2x=the longest piece of tubing
The total length of the piece of tubing is 12 inches, thus:
x + 2x = 12
Simplifying:
3x = 12
Dividing by 3:
x = 12 / 3 = 4
x=4, and 2x=8, thus:
The shortest piece is 4 inches long
The longest piece is 8 inches long
Answer:
a = 4
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos60° =
, then
cos60° =
=
=
( cross- multiply )
a = 4
6 is the constant of the equation
