Please help: Given: ∠4 is congruent to ∠2
Prove: ∠3 and ∠1 are supplementary

Statements and Reasons

See Below.

Step-by-step explanation:

We can write a two-column proof.

Statements:                                                Reasons:

                                                  Given

                                                  Vertical Angles are Congruent

                                         Linear Pair

                                         Substitution

                                         Substitution

                 Definition of Supplementary Angles

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

i think the amount would be $140.62
