X=5
Cos<span> 42° ~ 0.743
cos 42° = sin(90-42) = sin 58°
So sine of complementary angle also has same value as cos 42.
So sin 58 ~ 0.743

Answer:
x = - 6 ± 
Step-by-step explanation:
Given
x² + 12x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = 1 + 36
(x + 6)² = 37 ( take the square root of both sides )
x + 6 = ± ( subtract 6 from both sides )
x = - 6 ± ← exact solutions
Part A: Let x and y be the number of persons attending the two-day conference and y be the number of vouchers released. The equation that would best express the given is,
y = 4x
Part B: The number of people attending the conference is determined by dividing the given number of vouchers by 4. The answer is 956.
