Question 553680: I am buying an "A" frame trailer coupler. I am using it a little different than sometimes used. So I know that the angle of the the coupler is 50 degrees. I need to know that if I attach to steel channels to it, and it's going out at 50 degrees, about how far can I go until the width of the ends is about 70 inches.

To state it in plain mathematical terms, if I have a triangle where the top angle is 50 degrees, how far will the two sides be so that the bottom of the triangle is 70 inches long?

:
We know the two other angles will be = 65 degrees angles B & C
:
Using the law of sines where A=50 degrees, a = 70 inches, find b or c
=
=
=
Cross multiply
.766b = 70 * .9063
.766b = 63.44
b =
b = 82.8 ~ 83 inches, the length of the two sides, the ends will be 70 inches apart
