∩ stands for the intersection of the two arrays think a venn diagram in this it would be three
<span>∪ stands for objects that belong to either set
</span>
It would be A <span>∪ B because that set shows objects from both sets
If i'm wrong sorry its been a while since I've practiced or learned it</span>
The unit rate is 60 miles
Ok
First use the sine rule to find one value
b / sin B = c / sin C
20.2 / sin B = 18.3 / sin 38
sinB = 20.2 * sin 38 / 18.3 = 0.6796
m < B = 42.8 degrees
the other possible measure is 180 - 42.8 = 137.2 degrees

Answer:</h3>
34
<h3>
Step-by-step explanation:</h3>
KM is a transversal relative to parallel lines LM and KN. Thus ∠2 = ∠MKN ≅ ∠KML and ∠KML = ∠1. The two base angles of ΔKLM are equal, so that triangle is isosceles.
Then the ratios of all the sides are ...
... KL : LM : MN : KN = 8 : 8 : 8 : 9
The sum of these ratio units is 33, so each one stands for 132/33 = 4 perimeter length units. Then segment LM is 8×4 = 32 perimeter length units, and KN is 9×4 = 36 permeter length units.
The midsegment is the average of lengths LM and KN, so is ...
... (32 +36)/2 = 34 . . . . perimeter length units
