2. Koil and Karry want to order the figures from greatest to least
Tom [10]

Given:

Figures A, B and C.

To find:

The order of the figures and volume of each figure.

Solution:

<u>Figure A:</u>

Length = 10, Width = 2 and Height = 2

Volume of A = length × width × height

                     = 10 × 2 × 2

Volume of A = 40 cubic units

<u>Figure B:</u>

Length = 3, Width = 3 and Height = 1

Volume of B = length × width × height

                     = 3 × 3 × 1

Volume of B = 9 cubic units

<u>Figure C:</u>

Length = 6, Width = 3 and Height = 3

Volume of C = length × width × height

                     = 6 × 3 × 3

Volume of C = 54 cubic units

Order from greatest to least:

54 < 40 < 9

C < A < B

Hence Kurry said the correct answer.

yaroslaw [1]

Answer:

See Below.

Step-by-step explanation:

We are given that ∠1 and ∠7 are supplementary.

And we would like to prove that a is parallel to b.

  Statements:                                           Reasons:

\textbf{\textsf{1. $\angle 1$ and $\angle 7$ are supplementary}}              Given

\textsf{2. $m\angle3$ + $m\angle 7$ $= 180$}                               Supplementary Angles

\textsf{3. $\angle3$ and $\angle7$ are supplementary}                Definition of Supplementary

\textsf{4. }\bf{\angle 1 \cong \angle3}                                               Congruent Supplements Theorem

\textsf{5. }a\parallel b                                                      Corresponding Angles Converse

And we are done!
