Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
First off, the missing side is c=√(17²-8²)=15
sinø=opposite/hypotenuse=15/17
cosø=adjacent/hypotenuse=8/17
tanø=opposite/adjacent=15/8
cscø=hypotenuse/opposite=1/sinø=1/(15/17)=17/15
secø=hypotenuse/adjacent=1/cosø=1/(8/17)=17/8
cotø=adjacent/opposite=1/tanø=1/tanø=1/(15/8)=8/15
The answer is A because Alon could have rotated the figure and discovered that they are congruent
