0.25, 0.50, 0.74. It could be any of these numbers or any number between these numbers.
<span>plug in x=0 gives 0/0. This is one of the indeterminate forms (some others are ∞/∞ and 0·∞) use L'Hospital's Rule.
Differentiate the top and bottom of the fraction:
lim (cos x) / (x - π/2) => lim (-sin x) / (1 - 0)
Now you can substitute x = π/2 without problem
lim = -1/1= -1</span>
<span>A(<span>90∘</span>)=16sin<span>90∘</span>(cos<span>90∘</span>+1)=16×1×(0+1)=16 i think

Answer:
∠U = 31°
Step-by-step explanation:
∠W has an exterior angle next to it, making them supplementary angles. This means they equal 180° together. First, we solve for ∠W:
∠W + 84 = 180
∠W = 96
We know that ∠W is 96°.
We know that the sum of the angles of a triangle is 180°. Knowing that we can solve for ∠U:
96 + 53 + ∠U = 180
149 + ∠U = 180
∠U = 31
Therefore, ∠U = 31°
