Since t is from 0 to 1 second, the time length is 1 second total.
replace t in the given equation with 1 and solve for x:
x = 4 cos(PI x 1 + PI/4)
X = 4cos(PI + PI/4)
x = 4cos(5PI/4)
x = 4(-cos(PI/4))
x = -2√2
Answer:
20°
Step-by-step explanation:
Let x be the larger angle and y be the smaller angle.
Since they are complementary,
x+y = 90 => x=90-y
x+4y = 150
90-y+4y = 150
90 + 3y = 150
3y = 150-90
3y = 60
y = 20°
