Answer:
0
Step-by-step explanation:
cos(60) = ½
sec(60) = 2
sin(30) = ½
cosec(30) = 2
sin(0) = 0
2 - 2 - 0 = 0
last one because you can solve it to many way6s
Answer:
$38
Step-by-step explanation:
Since the last two numbers aren't over 50, we would round down. This leaves you with $38.
X² = 1/4 ⇒√⇒ x₁ = 1/2, x₂ = -1/2
