I thing is a None of the above
39 degrees. All angles must add up to 180 and the two acute angles equal each other because of the type of triangle it is!
Answer:
We actually can't answer this because we need at least one angle in the triangle. However, the unknown length has a range. And the range is:
3<C<9. This is from the triangle inequality.
Answer:
A=384 
Step-by-step explanation:
A =2(wl+hl+hw)
A=2(8*8+8*8+8*8)
A=2(64+64+64)
A=2(192)
A=384
