Answer:
Hypotenuse is 165.689
Step-by-step explanation:
For this question you will be using cosine.
You start solving this problem as C (cosine) = A/H (adjacent over hypotenuse).
COS(47) / 1 = 113/H
Meaning cosine of 47 over 1 is equal to 113 over H (hypotenuse).
Next you cross multiply leaving you with 113/ COS47 = COS47 x H
Next you divide both sides by COS47 x y
and divide 113 by COS47 and get your answer.
165.7 or 166
since the adjacent has already been given which is 113 you have to use the cos ratio to find the hypotenuse
cos47=adjacent/hypotenuse
cos47=113/h
cos47h/cos47=113/cos47
hypotenuse=166
I hope this helps
