Answer:
A
Step-by-step explanation:
Since cosine is positive and sine is negative that puts θ in Quad IV.
From right triangles we know:
Cos θ = adjacent/hypotenuse = 5/13
sin θ = opposite/hypotenuse = ?/13
To find the opposite side across from θ use the pythagorean theorem.
5² + y² = 13²
25 + y² = 169
y² = 144
y = 12
we are given that sin is < 0 so sinθ = -12/13
3(4 - x) <= 54
12 - 3x <= 54
-3x <= 42
x >= -14 answer
Its A
The change in temperature for 1 hour would be -5. hope this helps.
Hey!
How are you?? I'd love to assist you today :)
First, remove the parentheses.
Now you have <em>A/B + C/D</em>
Now, rewrite the expression with a common denominator.
AD + CB / BD
