Answer: The smallest number = 19
Step-by-step explanation:
We'll call X the smallest of those odd numbers
Then x + (x+2) + (x+4) = 63
X + X + 2 + X + 4 = 63
3X + 6 = 63
3X = 63 - 6 = 57
X = 57/3 = 19
The three consecutives odd numbers are 19, 21, 23
The sum = 19+21+23 = 63
Your answer : The smallest number = 19
Answer:
<u>Step-by-step explanation:</u>
Note the following identities: tan² x = sec²x - 1
tan² x + sec x = 1
(sec² x -1) + sec x = 1
sec² x + sec x - 2 = 0
(sec x + 2)(sec x - 1) = 0
sec x + 2 = 0 sec x - 1 = 0
sec x = -2 sec x = 1
