Answer:

Step-by-step explanation:

Use the Law of Cosines to find the measure of angle A from the lengths of the sides.

A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°

B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°

C = 180 - A - B = 95.3°

The post office will accept packages whose combined length and girth is at most 42 inches. (the girth is the perimeter/distance
Vilka [71]
If x represents the length of the box, then 42-x will be the girth. Since the largest area for a given girth is that of a square, the side length of the square cross section is (42 -x)/4.

The volume as a function of package length is then
.. v(x) = x((42-x)/4)^2
This has a maximum at x=14. The corresponding volume is 686 in^3.

Answer:

75.062cm^{2}

Step-by-step explanation:

To find the missing side use pythagorean theorem

So 6^{2} +b^2=8.5^2

Solve for b, b= 6.021

To find the area use \frac{1}{2}bh

So \frac{1}{2}(6.021+19)(6)= area

And you get 75.062
