I hope this helps you
at the 30-60-90 triangle has rules
30=>k
60=>k(square root of) 3
90=>2k
so in this triangle 60=> see 9
k(square root of) 3=9
k=9/(square root of) 3
2k=18/(square root of) 3
at the 45-45-90 triangle rules are
45=>2k
45=>2k
90=>[2k/(square root of 3)] (square root of) 2
x=[18/(square root of 3)].(square root of 2)
x=18(square root of 2)/square root of 3
Answer:
6108795
Step-by-step explanation:
To obtain the number of ways the committee can be selected :
4 teachers from the 12 teachers available and 3 students from the 43 students available
Using combinatorics :
12C4 * 43C3
recall :
nCr = n! ÷ (n - r)!r!
Using calculator :
12C4 = 495
43C3 = 12341
12C4 * 43C3
495 * 12341
= 6108795
