Answer:
x = 10
Step-by-step explanation:
note that sin30° = 
Since the triangle is right use the sine ratio to find x
sin30° =
= 
multiply both sides by x
x ×
= 5 ( multiply both sides by 2 )
x = 10

Answer:
f(x)=0
Step-by-step explanation:
For the function to be both even and odd, you must have ...
f(-x) = f(x) = -f(-x)
Adding f(-x) we have ...
2f(-x) = 0
Then dividing by 2 and recognizing f(-x) = f(x), we have ...
f(-x) = f(x) = 0
