Answer:
Number 7 is 34.56in
Step-by-step explanation:
First: Label each side Ex: Left side:
Top:
Bottom:
etc.
Second: Find the area of each side
Third: add them together
P.S. since this was a perfect cube, you could've also just found the area of 1 side then multiplied by 6:)
Answer:
it depends
Step-by-step explanation:
<em>Shino's formula will work for any prism</em>.
Angelo's formula will work for any prism whose base area can be found by ...
B = (1/2)ew
<em>Angelo can use this formula for a triangular prism</em>.
__
For a triangular prism, both may be correct.
For a prism of another shape, Shino is correct. (Angelo may also be correct, depending on the variable definitions.)
Step-by-step explanation:
20°+120°+I°=180°
I=40°
using sine rule,
I/sin I=x/sinX
12/sin40=x/sin20
x=12sin20/sin40
x=6.4
using similarly and enlargement,
we have, cw/cp=y/120
8/12=y/120
y=80°
Supplementary angles add to 180 degrees.
x+8x=180
9x=180
x=20
Find the supplement of an angle of 20 degrees
180-20=160
Final answer: 160 degrees and 20 degrees respectively
