Comparing the two triangle above, we can state:

a) The side WZ = side YZ
b) The side VZ = XZ
c) Angle WZV = Angle XZY (Vertical Angles)
d) XY is parallel to WV
e) So, Angle XYZ = Angle VWZ

Thus, we can conclude that the two triangles are exactly equal in measure. All the sides and angles of the triangle have the same measure.

So, Side WV = Side XY

12x - 61 = 3x + 2
12x - 3x = 2 + 61
9x = 63
x = 7

So, length of WV will be = 12(7) - 61 = 23

Thus, the answer to this question is 23

Brums [2.3K]

Answer:

Step-by-step explanation:

Given

There are 52 cards in total

there are total of 13 pairs of same cards with each pair containing 4 cards

Probability of getting a pair or three of kind card=1-Probability of all three cards being different

Probability of selecting all three different cards can be find out by selecting a card from first 13 pairs and remaining 2 cards from remaining 12 pairs i.e.

$=\frac{52\times 48\times 44}{52\times 51\times 50}$
