Complete the two-column proof by providing a reason for each of the five statements. Given: Rectangle R U T S Prove: ∠ U S R = ∠
Fantom [35]

Answer:

The two column proof can be presented as follows;

Statement                 {}                              Reason

1. RUST is a rectangle              {}              Given

2. RU = ST ; UT = RS             {}                  Definition of a rectangle

3. ∠STU and ∠SRU are right angles  {}    Definition of a rectangle

4. ΔURS ≅ ΔSTU                  {}                   By SAS rule of congruency

5. ∠USR = ∠SUT                 {}                     By CPCTC            

Step-by-step explanation:

Given that the side RU, the angle ∠SRU and the side RS of triangle ΔURS are congruent to the side ST the angle ∠STU and the side UT of triangle ΔSTU, then ΔURS is congruent to ΔSTU, by the Side-Angle-Side (SAS) rule of congruency

Therefore, we have that ∠USR ≅ ∠SUT and therefore, it can be shown that ∠USR = ∠SUT using the Congruent Parts of Congruent Triangle are Congruent (CPCTC) postulate.

The sum of three consecutive integers is 279. Find the integers
iVinArrow [24]

If all three were the same, then each one would be (279/3) or 93. The integers would be 93, 93, and 93.

Great ! Just take 1 away from the first one, and stick it onto the last one. Now you have 92, 93, 94, and the sum is still the same 279.

James went on a vacation and bought 8 meals for $10 each, 2 basketball tickets for $45 each, 2 baseball jerseys for $65each. Wri
inessss [21]
So 8 meals for $10 each , 2 tickets for $45 each, and 2 jerseys for $65 each
So (8x10) + (2x45) + (2x65) is the equation
And the answer is $300 because 8x10 is 80, 2x45 is 90, 2x65 is 130 and if you add it all up you'll get $300
80 + 90 = 170 + 130 = 300

Hope this helps! :)
