Answer:
sorry I don't know about it
Answer:
120
Step-by-step explanation:
Because we know that the line opposite of the right angle is flat, we know that 60 plus x must equal 180. Rewriting this gives us 180 - 60 = x.
Now, we can just solve for x.
x = 120.
Radius is the half of diameter.
That means the radius is 2inch/2=1inch.
Good luck mate!
<h2>
The Pythagorean Theorem</h2>
The Pythagorean Theorem: 
- <em>a</em> and <em>b</em> are the two legs in a right triangle
- <em>c</em> is the hypotenuse (the longest side of a right triangle; opposite the 90° angle
- <em>*keep in mind that this theorem applies only to right triangles</em>
<h2>Solving the Question</h2>
We're given:
- Legs = 9 units and 12 units
- Hypotenuse = <em>c</em>
<em />
Plug these measurements into the Pythagorean theorem:

⇒ Combine like terms:

<h2>Answer</h2>

Simplify by opening the bracket;
x(x^2+6y^2)
=
