Law of sines?? side c=22 side a=16 side b= 21 solve for angle c??? help

den301095 [7]

Answer:

Angle C measures: $71.52^o$

Step-by-step explanation:

When you know the length of the three sides of the triangle and not a single angle, the law of sines is of no use. You need to use the law of cosines. In your case, since you want to find angle "C", you use the following;

$c^2=a^2+b^2-2\,a\,b\,cos(C)\\2\,a\,b\,cos(C)=a^2+b^2-c^2\\cos(C)=\frac{a^2+b^2-c^2}{2\,a\,b} \\cos(C)=\frac{16^2+21^2-22^2}{2\,(16)\,(21)}\\cos(C)=0.3169643\\C=arccos(0.3169643)\\C=71.52^o$

A box has a volume of 144 in3 and a height of 4 1/2 in.What is the base area of the box?

Zepler [3.9K]

Box volume can be computed by getting the base area multiplied by the total height.

in formula for volume we have,

V = Base Area x H. Given the Volume of 144 cu in and H = 4.5 in. we can solve for Base Area (BA)

Volume (144 cu in) = BA x Height (4.5 in)

BA = 144 cu in/4.5 in

Base Area = 32 square inches
