oobleck, what do you mean I thought that's what this website is for.
Well, let's see, sin(42°) is not a clown-friendly angle, but we'll do our best to entertain you! Now, if we're looking for the value that's equivalent to sin(42°), we can't just clown around. The correct answer is:
d. cos(48°)
Why? Because sin(x) and cos(y) are complementary angles when x + y = 90°. So, if sin(42°) is equal to x, then cos(y) can be equal to cos(48°), making them a clown-tastic pair.
To determine which value is equivalent to sin(42∘), we first need to recall the relationship between sine and cosine.
The trigonometric identities state that sin(θ) = cos(90∘ - θ) for any angle θ.
Therefore, sin(42∘) is equivalent to cos(90∘ - 42∘).
Simplifying this expression, we have cos(48∘).
Hence, the correct answer is option d. cos48∘.
clearly not B
C'mon, GROOVE - this is just a homewok dump isn't it? No input of any kind on your part. Just study your basic trig functions.
