Answer:
A. ~14.3 B. ~9.93
Step-by-step explanation:
A.
By looking at the equation you can see that you need to find the tan of the angle so the equation will be "Tan 40= 12/x" which you can simplify to "X=12/Tan 40" which equals "about 14.3"
B.
This one is very similar
By looking at the equation you can see that you need to find the Cos of the angle so the equation will be "Cos 25= 9/x" which you can simplify to "X=9/Cos 25" which equals "about 9.93"
