Question 198586
How long is the third side of a triangle when each of the other two sides are 4 feet 7 inches and there is an angle of 22.5 degrees between the two sides given
--------------------
2 sides are 55 inches.
The bisector of the 22.5 deg angle forms 2 right triangles, and the hypotenuse is the 55 inches.
The side opposite is 55*sin(11.25) = ~ 10.73 inches.
That is 1/2 the 3rd side, so it's
21.46 inches.
