 Homework Statement:

I was told to be specific, so here it is:
Can you please help me answer this question that was given to me in the physics practice study guide? I am confused about this one and how to do so I would like someone to explain and walk me through how I should do this. Everybody keeps on telling me to reword this question and this is my second day just trying to ask a question on this platform. Can someone please help me out and I love you and I highly appreciate it if you did. Taking AP Physics 1 is quite challenging as a high schooler.
Roy pulls up at an angle on a rope attached to a crate to move the crate across a horizontal floor. The mass of the crate is 20.6 kilograms, Roy applies 115 newtons of force at an angle of 26.7 degrees, and the coefficient of kinetic friction between the crate and the floor is 0.349.
a. How hard does the floor push up on the crate?
b. What is the acceleration of the crate?
 Relevant Equations:
 f = mu x N
I drew out a motion diagram and used 115N sin(26.7 degrees) = 51.7 N but It turns out to be wrong.
