Answer:

4(2+\sqrt{2})\text{ square unit}

Step-by-step explanation:

Given function that shows the area of the opening,

A(\theta)=16 \sin\theta (\sin \theta + 1)

If \theta = 45^{\circ}

Hence, the area of the opening would be,

A(45^{\circ})=16 \sin 45^{\circ} (\cos 45^{\circ} + 1)

=16\times \frac{1}{\sqrt{2}}\times (\frac{1}{\sqrt{2}}+1)

=16(\frac{1}{2}+\frac{1}{\sqrt{2}})

=8+\frac{16}{\sqrt{2}}

=8+4\sqrt{2}

=4(2+\sqrt{2})\text{ square unit}

A rectangle has a length that is 12 centimeters longer than its width. Let x represent the width of the rectangle. Which of the
alexdok [17]

I can't see your answer options, but the answer to this question is x + 12 cm.

We can find this because if the length is 12 cm longer than the width, and the width is 'x' cm, the length has to be x + 12 cm, because this is how you represent something being 12 more than a width. For example, 12 more than 6 is 12 + 6 = 18.

I hope this helps!
