a. Angles ABC and CBD are supplementary, so you know that m\angle ABC=180^\circ-24^\circ=156^\circ

The interior angles of any triangle sum to 180 degrees in measure, so that m\angle ACB=180^\circ-156^\circ-16^\circ=8^\circ.

By the law of sines, we then have

\dfrac{\sin8^\circ}{7600\,\mathrm{ft}}=\dfrac{\sin16^\circ}{BC}\implies BC=\dfrac{(7600\,\mathrm{ft})\sin16^\circ}{\sin156^\circ}\approx15052\,\mathrm{ft}

b. In triangle BCD, we have

\sin24^\circ=\dfrac{CD}{BC}

and so

CD=\sin24^\circ\dfrac{(7600\,\mathrm{ft})\sin16^\circ}{\sin8^\circ}\approx6122\,\mathrm{ft}

zloy xaker [14]

Answer:

442554 square miles

Step-by-step explanation:

The area of a triangle is given by :

0.5*A*B*Sin(∅) where A and B are two sides and ∅ is the angle between them.

We will find ∅ by applying cosine rule:

c^2 = a^2 + b^2 − 2ab cos(∅)

Where ∅ is angle between sides a and b.

In this example:

a=1028, b=1046, c= 965

Plugging in the values, we get ∅=55.4°

Applying the formula for Area:

0.5*A*B*Sin(∅)

0.5*1028*1046*Sin(55.4)= 442554 square miles

Kyle is shopping for his favorite
nalin [4]

Answer:

The 9 ounce box is the better deal, and Kyle will save 2 cents.

Step-by-step explanation:

First, you should find how much 1 once would cost in the 9 ounce box.

Do 2.52 ÷ 9 = x

x = 0.28

This means that in the <u>9 ounce box, one ounce costs 28 cents</u>.

Now, find how much one once would cost in the 12 ounce box.

3.60 ÷ 12 = x

x = 0.30

This means that in the <u>12 ounce box, one ounce costs 30 cents</u>.

This means that the 9 ounce box is a better deal, because it costs less per ounce.

0.30 - 0.28 = 0.02. This means there is a 2 cent difference in their prices per ounce.

So, Kyle should choose the 9 ounce box, and he will save 2 cents per box.
