Angles and Parallel Lines
... (3x – 3)o and 66o are linear pairs and sum to 180o. (3x – 3)o + 66o = 180o 3x + 63 = 180 3x = 117, x = 39 (4y + 2)o and 66o are congruent alternate interior angles. (4y + 2)o = 66o 4y = 64, y = 16 (3x–3)o and (2z)o are congruent alternate interior angles. (3x–3)o = 3(39) – 3 = 114o (2z)o = 114o, z = ...

5 Trigonometric Functions H
... *The Babylonians were the first to subdivide the circumference of a circle into 360 parts. There are various theories as to why the number 360 was chosen. One is that it is approximately the number of days in a year, and it has many divisors, which makes it convenient to work with. Another involves ...
