Let x = angle
180 - x will then be the supplement.
Set up the equation:
x = 2(180-x)-15
x = 360 - 2x - 15
3x = 375
x = 125 and its supplement is 180-125 = 55
Prove it: 55 x 2 = 110 + 15 = 125
125 + 55 = 180

Existence of Right Angle in Hilbert Axioms
Hilbert, in Foundations of Geometry briefly mentions that the existence of right angles is a corollary to the supplementary angle theorem. (i.e. If two angles are congruent, then their supplementary angles are congruent).
How does existence of right angles follow from this?

Prove that the intersection angle between the Simson lines of two triangles inscribed in the same circle it's the same for any point.
Suppose the triangles ABC and DEF share the circuncircle C, and P and Q are any diferent points on C. Let l, m be, the Simson lines of P related to ABC and DEF, and p, q the Simson lines of Q related to ABC and DEF, then i must prove the angle between l and m equals the angle between p and q.
I just have one Theorem about the Simson line:
Theorem: Let P, Q be two points on the circuncircle, C, of the triangle ABC. Let l, m be their respective Simson's lines. Then the angle between l an m equals to the half of the central angle POQ, where O is the center of C.

Pythagoras: Get b when only a and angle α are given
Given the Pythagoras Theorem: a 2 + b 2 = c 2
Is there a way to get the value of b when we only have a value for a and the angle α?

How do you find a point on a line bisecting an angle in three-dimensional space?
Given the x, y, z coordinates of three points P 1 , P 2 , P 3 with the angle between them being P 1 P 2 P 3 , how do you find a point, say at a distance of 1 from P 2 , on the line that bisects the angle?I know from the angle bisector theorem that the point must be equidistant from the the vector ( P 3 P 2 ) and ( P 1 P 2 ), but I can't seem to figure out how to find such a point in 3-space.
