The answer is C! Annuity means "a fixed sum of money paid to someone each year", which is similar to what the letter C is suggesting.
68+70=180
=138=180
=180-138
=42 degrees (using angle sum property of triangles
Hope this helps you
If this is a cube and each side is 6ft, each face will have an area of 6ft * 6ft, or 36ft. There are 6 faces on a cube, so 36ft * 6 = 216ft² as the surface area (it's also the same as 6³, fancy huh?)
It is 255 cm^2
This is a very basic area problem. You should try refreshing on some of your multiplication and addition skills. Try reading patterns, maybe. Also learning geometric proofs is VITAL.
