Hello! I'm not really a math person but I have a trigonometry problem I'm struggling with to get some values for a physical project I'm building. I'd love a calculator that I can punch values into, but not sure what the right words are to find one, and not sure how to solve it manually either.

Essentially, I have 2 triangles, with 4 variables, which are as follows:

side = 2

a = 100°

d = 25°

relation = 2

And then here are the additional parameters/rules:

A = D = side

B = E

C = F - relation

Photo attached for a visual if that is helpful!

Is there an online calculator already that could solve this sort of problem for me? If not, what are the steps to go about solving this? I haven't done trig for many years (since high school) so I'm a bit rusty. I anticipate having to solve this with a couple different values in the variables, but the whole thing is hard for me to wrap my head around.

Tysm in advance, I appreciate the help!

Just moved into this place and there's a big hole underneath the built-in window valence (not my thing, personally would remove it if possible but alas.)

​

The crack and hole are on the inner side of the valence (not the window/wall side), not sure what could have caused them... old building though.

​

What would be the best way to fix this? (and/or diagnose it properly?)

​

Currently it is home to a large cellar spider so I have a feeling there's bugs that are trying to get in through there...

​

Thanks in advance!
