They would need to buy 5 dozens because the area is 56 and 12 times 5 is 60.
A.
because the total distance of every triangle 180. Add the two other angles so 42+ 57 =99. Then you have to subtract those two combined angles to find the missing one from the total distance, which is 180. 180-99=81. the answer is A. 81
<span>4 9/10 divided by 2 3/5
</span>4 9/10 = 49/10
2 3/5 = 13/5
so
(49/10) / (13/5)
=49/10 * 5/13
= 49/26
or
= 1 23/26
2 would be the base and 3 will be the square
