I am building an A-frame PVC greenhouse. I plan to make the pitch 45 degrees for each side. I have a 10 foot gap across from each side of the wall.
How do I calculator the exact length of each half of the roof? I know there's Pythagoras Theorem (a2 +b2 = c2) but I am unsure how to apply it because I only know "A" and the 45 degree Angle, but not "B" or "C".
Thanks for any help!!
If it's a 45 degree angle, B=A.
Or you can set any value you please for roof height. You don't need to know any trig, nobody cares what the angle is. People who do roofs work in rise/run ratio, not angles.
