The diagonals of a rhombus are 16 cm and 12cm. find its length
1 answer:
Answer:
l=10 cm
Step-by-step explanation:
In a rhombus, the diagonals are cut into identical lines at the intersection.
This way, I found the measures of the halves of the diagonals in a right triangle, knowing that the diagonals of the rhombus are perpendicular on each other.
I calculated that AO = AC/2= 8, and that BO=BD/2= 6, and then I applied pytagora's theorem in a quarter of the rhombus, which is the right triangle AOB, to find the length of a side

Answer:
In 16170 ways the committee can be formed.
Step-by-step explanation:
3 faculty members and 5 students are required to form a committee.
The eligible to serve on the committee are 7 faculty members and 11 students.
If each committee position has the same duties and voting rights.
Then, the number of ways of selecting 3 faculty members out of 7 eligible faculty members is .
Again, the number of ways of selecting 5 students out of 11 eligible students is given by .
Therefore, in (35 × 462) = 16170 ways the committee can be formed. (Answer)
