Answer:
Step-by-step explanation:
cos²<em>x</em> = 1-sin²<em>x</em> = 1-(5/13)² = 144/169
cos<em>x</em> = √(144/169) = 12/13
tan<em>x</em> = sin<em>x</em>/cos<em>x </em>= (5/13)/(12/13) = (5/13)×(13/12) = 5/12
I think best word to insert in the blank is the term "bisecting".
An altitude of a triangle is a line or segment that passes through a vertex of the triangle and is bisecting <span>to the line containing the opposite side.
</span>"Bisect<span>" means to divide into two equal parts which is true for the altitude of a triangle.</span>

Sorry but your question is not too explanatory but I sure hope this helps
