You need to add 2+3+4
divid into 1/3
and your answer is 0.037 longated
Answer:
383.4 km
Step-by-step explanation:
The interior angle at the first turning point in the triangular flight path has measure 270° -215° = 55°. The law of cosines can be used to find the length of the final leg:
c² = a² +b² -2ab·cos(C)
c = √(125² +137² -2·125·137·cos(55°)) ≈ √14749.01 ≈ 121.4
The total length of the journey is then ...
round trip = 125 +137 +121.4 = 383.4 . . . km
___
In the attachment, the number at the bottom is the sum of the lengths of the two adjacent sides. The total length is then 125 +258.4 = 383.4 km.
Answer:
12/17
Step-by-step explanation:
total number of marbles that are purple (11) plus the total number of marbles that are not small (15) minus the number of marbles that are both purple and not small (2)
11 + 15 - 2 = 24
over the total number of marbles (34)
24/34 simplifies to 12/17
