2 answers:
Answer:
Option D.
Step-by-step explanation:
The given triangle is a right angle triangle having two angles 60° and 30°.
One of the legs is given as 3 units.
We have to find the length of the side opposite to the angle measuring 60°
We will find the tan of this angle to get the required side.
x = 3(tan60)
x = 3√3
Therefore, Option D. 3√3 will be the answer.

Step-by-step explanation:
If there are <em>n</em> students, then the number of pairs is .
With 12 students, pairs can be formed.
The reason the formula works is this: Each of the 12 students can be paired with 11 other students (no student is paired with him/her self). But counting 12 x 11 = 132 counts each pair <u>twice</u>. Example: student A can be paired with student B,..., student B can be paired with student A. The pair was counted two times.
See the attached image that shows pairings of 5 students. There are
5(5 - 1)/2 = 5(4)/2 = 10 pairs.
