DONT COMMENT IF YOU DON KNOW

Answer:

okay so im not sure which is being round so i'll do both

if you are going to round the miles and gallons:

278.2 to 278 because the decimal is below 0.5

19.6 to 20 because the decimal is above 0.5

278/20 = 13.9 which you would round to 14 because the decimal is above 0.5

if you are only going to round the answer:

278.2/19.6 = 14.193877551 which you would round to 14 because the decimal is below 0.5

so regardless of what you do, <u> your answer will be 14</u>

Look at the figure. Name the postulate or theorem you can use to prove the train goes congruent?
Nikolay [14]

Let us recall parallelogram properties, which states that opposite angles of parallelogram are congruent.

We can see from graph that side US is parallel to TR and measure of angle U equals to measure of angle R, therefore, quadrilateral drawn in our given graph is a parallelogram.

Since we know that opposite sides of parallelogram are congruent. In our parallelogram UT=SR and US=TR.

In our triangle STU and triangle TSR side TS=TS by reflexive property of congruence.

Therefore, our triangles are congruent by SSS congruence.
