Answer:
75°
Step-by-step explanation:
In triangle FBG, one angle is 36. That means the other two must total 180-36=144. Assigning each one 72, their supplementary angle on the interior of the pentagon would be 108.
In triangle JDI, one angle is 39. That means the other two must total 180-39=141. Assigning each one 70.5, their supplementary angle on the interior of the pentagon would be 109.5
We now have 4 of the interior angles. Pentagons have an interior total of 540. 540-108-108-109.5-109.5=105
x is the supplement of 105. 180-105=75
Answer:
6 bags.
Step-by-step explanation:
We have been given that trail mix is sold in 1-pound bags. Mary will buy some trail mix and repackage it so that each of the 15 members of her hiking club gets one 2/5 bag.
Let us find the number of pounds Mary will need to give to 15 members. As Mary wants to give 2/5 of 1 ounce bag of trail mix, so she will need 15 times 2/5 ounces to given to 15 members of her hiking club.
So Mary needs 6 pounds of trail mix to give to 15 members of her hiking club. As trial mix is sold in 1-pound bags, therefore, Mary should buy 6 bags to have enough of trail mix without any trail mix left over.
Answer:
