Use the law of sines to find the value of w.
Lunna [17]

Option B: 4.0 cm is the value of w

Explanation:

It is given that \angle W= 39, \angle U=31, VW=3.3 and UV=w

Using the law of sines, we have,

\frac{sin U}{3.3} =\frac{sin W}{w}

Substituting the values, we have,

\frac{\sin 31}{3.3}=\frac{\sin 39}{w}

Cross multiplying, we get,

(sin31) w=3.3( \sin 39)

Simplifying, we have,

0.515w=2.077

Dividing both sides by 0.515, we have,

w=4.0

Thus, the value of w is 4.0 cm

Hence, Option B is the correct answer.

Please help, I'm really confused with these two questions ):
erik [133]

Step-by-step explanation:

The die is rigged, so "not 3" is not a possibility.  Ruling out those branches of the tree, there are 4 possible outcomes, one of which is the desired outcome.  So the probability is 1/4.

A fair die has six sides that are equally likely, so the probability of rolling more than 2 is always 4/6.  The outcome of the first roll does not effect the outcome of the second roll.
