The answer is in the attachment
Volume = Length x Width x Height
Volume = 8 x 5 x 2 = 80 in³
Answer: 80 in³
The ratio 21:28 in it's simplest form is 3:4
If angle TSV=6x+17 then arc it intercept (SV)would be double it
6x+17=1/2 (15x+13)
12x+34=15x+13
21=3x
x=7
Arc SV=15(7)+13
=118
And angle TSV=6(7)+17
=59
There are 360 degrees in a circle and the measure of the arc would be equal to the central point so the sum of all the arcs equals 360
Arc SV+ arc SUV=360
118+SUV=360
Arc SUV=242
