7. Examine the triangle below: WHAT GivES PEOPLE FEELINGS OF POWER The red-dotted zig-zag path continues forever with each zig making an angle of t/4. If possible, calculate the total length of the red-dotted zig-zag line. (oh, it's possible...) You may assume that the large blue triangle is a right triangle. Hint: you'll to use some special triangle knowledge, some trigonometry and create two infinite series. continued... : ; 1 = -1 8. Find the value of if E T 2 . Hint: consider the series (: ) as a convergent geometric (1+)' nelt n=3 series
