Answer:
Step-by-step explanation:
<u><em>( 8 ).</em></u> m∠1 = m∠ 4 = m∠ 5 = <em>m∠6 = 52°</em>
<em><u>( 9 ).</u></em> m∠ 2 = m∠ 3 = <em>m∠ 7</em> = m∠ 8 = 180° - 52° <em>= 128°</em>
divide total miles by total time:
60.9 / 3.5 = 17.4 miles per hour
Substitute the numbers in the equation:

Since L=5in, W=4in and H=8in:

Therefore, the volume is equal to 160 inches cubed.
