Answer:
147 in2
Step-by-step explanation:
(Assuming the height is 4 1/2 inches = 4.5 inches)
We need to calculate the area of all six faces of the prism
Two faces have the sides 8 and 3, which area is 8*3 = 24 in2
two other faces have the sides 8 and 4.5, which area is 8*4.5 = 36 in2
the two last faces have the sides 3 and 4.5, which area is 3*4.5 = 13.5 in2
So, summing up all the areas, we have:
24 + 24 + 36 + 36 + 13.5 + 13.5 = 147 in2
Answer:
12
Step-by-step explanation:
4 x 3 = 12
Answer:
are corresponding angles and are congruent to each other.
are alternate exterior angles and thus congruent to each other.
are interior angles on the same side, and they are supplementary(sum=180°).
Step-by-step explanation:
Given:
Line 
Line
is traversal.
By angle properties we can name the angle relationship of given angle pairs.
are corresponding angles and are congruent to each other.
are alternate exterior angles and thus congruent to each other.
are interior angles on the same side, and thus they are supplementary.
