Polar to rectangular conversion

Old age & I've forgotten how. Or I went brain dead...........
8 degree slope & 150 feet long on the diagonal, what's the height @ the
back? Please?

Appreciate that Roy. I about had a stroke on your 1st answer. LOL
I "used" to have a Radio Shack calculator that did P~R & R~P conversion I
used with a Land Surveyor. I never could do trig stuff but could do the
other.

Aren't we on a CAD group here? (Not that I mind OT stuff at all...)
Don't you just draw the geometry you know?

 

Mine too!

(My comment was intended to say that I never have to worry about sine,
cosine, etc since CAD. Once in a while you have to understand geometry to
lay something out, but I never have to resort to calculation to determine
the length of something...I just draw it, then LIST or dimension it.)

 

Aw C'mon Michael, ease up........in fact, didn't I see some postings from
you on Corel that were essentially the same premise?
;-) Who better to ask then here for the wisdom & knowledge? Uhh, you did
have the answer didn't you? I brain~farted and admitted it! I guess I
could have went to the Excel group or something..???............

Relax, it's a whole new day..........Dan

 

**Guess you musta been 'inside the dog' at the time.**

 

Don't know what thread you're referring to on Corel groups, but I can only
understand the question if the poster *doesn't* have a cad package at all.
(My abilities with CorelDraw are so limited that I don't know if I could
even do that in that application.)

In order for me to come up with the answer as quickly as possible I would
have had to draw it, then inquire from the model. I was never very good with
those trig tables....but I can solve that problem with 2 commands using CAD.
I even resort to CAD to help me with compound miter cuts in wood. I'm a bit
of a blockhead that way.

Frankly, I never even thought of drawing it out. I just remembered from my
surveying days of the P~R conversion and knew it could done in about 6
seconds. And like you, I'm no good with the trig tables either. Albeit it
did take me about 2 minutes to draw it out. But I liked Roys solution
better.
150*sin(8) = 20.87596514....

That's the easiest way to do it that I can see
