find theta

[swift pawn]

Is it possible to find theta or do I need more information?

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Hmm 45?

I think we need more info like for example the base length of the right triangle

[swift pawn]

Could you explain a little more?

[dense junco]

can you explain a bit what you don't understand first

[swift pawn]

I don’t understand how drawing the circle helps

[swift pawn]

Still don’t get it, sorry @dense junco

[dense junco]

treat θ as an independent variable
the side opposing θ is a dependent variable
construct a circle with this side as the diameter
at the left endpoint of this side, construct a circle with diameter 13.9

take the lower intersection point of these two circles.
this point, by construction, lies on the red circle, so you have the desired right-angled triangle with 13.9 as the length of one side

Ah okay thanks, sorry I’m a little slow.
