The quadrilateral is cyclic, because the angle that the tangent and the radius meet forms a right angle. Since the two opposite angles are 90° each, they form a 180° summation. Thus, the four points are cyclic.
Now, the smaller ∠O is 135, which means x is 180 - 135 because the four points are concyclic. Thus ∠O + x = 180°
Hence, x = 180 - 135 = 45°
∴ x = 45°

Answer:
Step-by-step explanation:
6 is common to both terms, so 6x - 18y is equivalent to 6(x - 3y).
Find the slopes of the segments and then use the decimal form of the answer to figure out the shortest part of the triangle. ( p.s. the triangle is not drawn to scale, so you can't use the graph to determine the shortest part)
