<u>Answer:</u>

<u>Step-by-step explanation:</u>
To find the solution to the equation, we have to rearrange the equation to make
the subject:

⇒
[Subtracting 2 from both sides]
⇒ 
⇒
[Subtracting
from each side]
⇒ 
⇒
[Diving both sides by 213]
⇒ 
I think it would be division :)
g(x) –f(x) = 3x –9 - (<span>5x –1)
</span> g(x) –f(x) = 3x –9 - 5x + 1
g(x) –f(x) = -2x - 8

Answer:
- Long leg = 10√3
- Short leg = 10
- Hypotenuse = 20
Step-by-step explanation:
<u>Concept: </u>
Here, we need to know the idea of a special triangle 30-60-90.
A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist.
The ratio between the corresponding side of each angle is 1 : √3 : 2
If you are still confused, please refer to the attachment below for a graphical explanation.
<u>Solve:</u>
30-60-90 ⇔ 1 : √3 : 2
Given the side corresponding to 90° is 20
30° : 90° = 1 : 2
30° : 20 = 1 : 2
30° = 10
30° : 60° = 1 : √3
10 : 60° = 1 : √3
60° = 10√3
Hope this helps!! :)
