Answer:
a. tanB= 3/2
Step-by-step explanation:
tanA= p/b =:2/3
For angle A,
p= 2
b=3
For angle B,
p = 3
b=2
So, TanB = 3/2
Answer:
f. none of the above
Step-by-step explanation:
90 + 63 = 153
180 - 153 = 27
∠A = 27°
Answer:
10 i think
Step-by-step explanation:
Answer:
4.4 * 10^21
Step-by-step explanation:
Given :
Number of pop, n(p) = 10
Number of reggae, n(r) = 25
Number of blues, n(b) = 10
Total number of songs to select (n) = 15
If she wants equal Number if the 3 genres
Each genre will have : 15/3 = 5 songs each
Hence,
(10C5 * 25C5 * 10C5) * n!
Combination formula :
pCr = p! / (p-r)! r!
Using calculator to save computation time :
(10C5 * 25C5 * 10C5) * n!
(252 * 53130 * 252) * 15!
= 4412050844368527360000
= 4.4 * 10^21
