42 if you multiply 6 and 7 it's 42 and multiply 21 and 2 and it will be 42 so that's the common denominator
Multiply 5.2 x 30 and you get 156 miles

31.12 in
<u>Explanation
</u>
To get the length required, lets first find angle mF,
mF = 180 – (43 + 62) =75o
Now we can use the sin rule to find length DE.
a/sinA =b/sinB Where a and b are the length opposite to angle A and B respectively.
DE/sin75=22/sin43
DE=(22 sin75)/sin43
DE=31.12 in
