I need help with the second one and I tried the others but I'm not sure if the answers I got are correct. I need to use trigonometry and I have a difficult time with it. Please help with these. Thanks in advance.

First one.....good!!!
Third one.......good!!
Last one......
We know the adjacent side to the angle and we need to find the hypotenuse
Thw cosine relates these
So we have that
cos 67° = 5 / x rearrange as
x = 5 / cos 67° ≈ 12.8
