It would cost $20.12 because if you multiply $4.47 by 4 pounds you would get 17.88. Then, you would divide $4.47 by 2 and get 2.235 but round that number up to $2.24. After adding $17.88 and $2.24 together, you recieve a total of $20.12

Hope this helps you!

Could someone help me with this trigonometry question.

Aleksandr-060686 [28]

Answer:

About 75 degrees

Step-by-step explanation:

Let's call the point between C and B D. Using the Pythagorean Theorem, you know that CD is $\sqrt{112}$ cm, meaning that BC has length $8+\sqrt{112}$ cm. Additionally, we know that AB has length $\sqrt{208}$ . Using the law of cosines:

$(8+\sqrt{112})^2=16^2+208-2(16)(\sqrt{208})\cdot \cos(A) \\\\345.328=256+208-461.511\cos(A) \\\\-461.511\cos(A)=-118.672 \\\\A=\cos^{-1}(0.2571)\approx 75^{\circ}$

Hope this helps!
