Corresponding angles of congruent triangles are equal.
A triangle's three angles add up to 180 degrees.
Answer: 13 cm^3
Step-by-step explanation:
The volume of a rectangular prism is the height*width*length.
3 1/4 as a decimal is 3.25.
Now we can plug in the given values into the formula for the volume.
Therefore, the volume = 3.25 cm * 4 cm * 1 cm
= 13 cm^3

=57 times 4/57 times 2
=57/1 times 4/57 times 2
=4/2 times 2 (cancel common factor:57)
=4/1 times 2 (convert element to fraction 2= 2/1)
=4/1 times 2/1
Multiply the numbers (4 times 2)
=8/1 times 1 (Multiply the numbers 1 times 1)
Apply the fraction rule: a/1 =9
=8
