Answer:
my opinion is A hope it helps
The denominator of the rational expression 600/(x-4) is x-4.
We know x represents Sarah’s average speed. So x-4 will also represents the average speed. And x-4 represents 4 mph less than the average speed of Sarah, x.
Therefore, option a) is correct.
Answer:
<1 : 36 degrees
<2 : 90 degrees
<3 : 36 degrees
<4 : 54 degrees
Step-by-step explanation:
First off, rhombus's have right angles formed at the middle, meaning that <2 is 90 degrees. Then, it's given that angle is 54 degrees, and its alternate interior angle is the one that is adjacent to <3. To find <1, add 90 and 54, and subtract that from 180. So <1 is 36 degrees. So that automatically makes < 3, 36 degrees and < 4, 54 degrees.
