From the law of sines, we have:

,
where x and y are the sides opposite to angles X and Y, respectively.
Substituting the known values, we have:

, thus

.
Using a calculator, we can find that arcsin(0.31)=18 degrees, approximately.
We know that sine of (180-18)=162 degrees is also 0.31. But 162 and 51 degrees add up to more than 180 degrees.
Thus, there is only one triangle that can be formed under these conditions.
Answer: 2.25x

Scientific notation is used in science because the number can be vary from so much that using decimal is making it hard. The number expressed in

form. Both number in the question is already in scientific notation. Then to multiply the number and keep it at scienfitic notation the calculation should be:
2.5 x

x 9 x

= 22.5 x

= 2.25x
Answer:
-8
Step-by-step explanation:
Answer:
There can be at most
attendees in a corporate team-building event.
Step-by-step explanation:
Let
denotes number of attendees in a corporate team-building event.
Fixed cost = $19
Cost charged per attendee = $1
Budget for the corporate team-building event = $31
Therefore,

So, there can be at most
attendees in a corporate team-building event.
