# Question:Numerical value for some quadratic equation.

## Question:Numerical value for some quadratic equation.

Maple

I have this piece of command in maple which I want to get a numerical value out of it, but instead of that it shows the sines without their numerical values. What to add to these commands to get a numerical value for x? (I checked maple's help for "numerical value", but perhaps I am a bit impatient and didn't find such a thing):

with(Degrees);
solve(x^2 = (4/sind(10))^2 + ((4 + x)/sind(20))^2 - 8*(4 + x)/(sind(10)*sind(20)), x);

I get the following:

1                        /  /
---------------------------------------------- \8 \16
2
4 Degrees:-sind(10)  - 4 Degrees:-sind(10) + 1

2                                        2
Degrees:-sind(10)  Degrees:-cosd(10) - 8 Degrees:-sind(10)  -

/                     4                  2
\256 Degrees:-sind(10)  Degrees:-cosd(10)

4
- 192 Degrees:-sind(10)  Degrees:-cosd(10)

4
+ 32 Degrees:-sind(10)

3
- 64 Degrees:-sind(10)  Degrees:-cosd(10)

3
+ 24 Degrees:-sind(10)

2
+ 16 Degrees:-sind(10)  Degrees:-cosd(10)

\      \\
- 2 Degrees:-sind(10)/^(1/2)//,

1                        /  /
