the write answer is d

bcoz the ground is already applying the normal force, which is equal to mg=49N

then, after calculating the vertically downward components of 2 forces working on the triangular block, we get

=24+32=56N

the ground will apply the total normal force equal to mg+sum of components of forces acting on block

=49+56=105N

mark as brainliest
