Triangle ABC is inscribed in the circle and AC = AB. The measure of angle BAC is 42 degrees and segment ED is tangent to the circle at point C. What is the measure of angle ACD? I know the formulas, but I don't know how to get angle ACD. Can someone help me?
Angle bisectors TX and UY of triangle TUV meet at point I. Find all possible values of angle V if angle. As your answer, enter the number of degrees in angle V. If you find more than one possibility, list the possible values in increasing order, separated by commas. What is the answer to this problem and how do you work it?
Let ABC be any triangle. Equilateral triangles BCX, ACY, and BAZ are constructed such that none of these triangles overlaps triangle ABC.
a) Draw a triangle ABC and then sketch the remainder of the figure. It will help if ABC is not isosceles (or equilateral).
b) Show that, regardless of choice of ABC, we always have AX = BY = CZ.
Problem A I can manage(obviously), but I dont know how to do B. If I made ABC an equilateral triangle, it would be easy, so I dont want to do that. Could you explain how to prove if ABC was obtuse scalene?
On the first problem, it goes like this. One over the square root of 100 plus the square root of 102. That is added to one over the square root of 102 plus the square root of 104. This continues all the way to one over the square root of 9998 plus the square root of 10000.
Could someone explain how to do these problems?

Penn writes a 2013-term arithmetic sequence of positive integers, and Teller writes a different 2013-term arithmetic sequence of integers. Teller's first term is the negative of Penn's first term. Each then finds the sum of the terms in his sequence. If their sums are equal, then what is the smallest possible value of the first term in Penn's sequence?
