Answer:
30,60,90
Step-by-step explanation:
A triangle’s interior angles sum to 180.
1:2:3 ratio
180 divided by 6 (add up the ratio numbers)= 30. Use 30 in the ratios.
(30x1=30, 30x2=60, 30x3=90)
30,60,90
30+60+90=180 (add back up to make sure they sum to 180 to check your answer)
The volume V of a prism can be found by:
The volume of a rectangular prism can be found through:

Where l is the length, w is the width, and h is the height.
The height can be found by rearranging the equation to:

Take the volume (1374.28) and divide it by the length times the width (9.4*17.2=161.68).
1374.28/161.68=
8.5 inches is the height of the prism.
