Answer:
x = 31
Step-by-step explanation:
The 2 sides are congruent, meaning the 2 angles are equal so:
47 = x + 16
subtract 16 from both sides
31 = x
Answer: The speed of Bob is 56.8 km/hr.
Step-by-step explanation:
Let the speed of Bob be 'x'.
Let the speed of John be 'x-8'.
Distance covered = 230 miles
time = 
According to question, we get that

Hence, the speed of Bob is 56.8 km/hr.
I could be wrong but I believe it would be 35.
Answer:
gets smaller.
Step-by-step explanation:
Quick Answer
To give you a short quick answer, the supplement is going to have to decrease or get smaller.
Example
Suppose the acute angle is 10 (anything under 90 will do).
Then the supplement is going to be 180 - 10 = 170
Now suppose the acute angle increase to 50 degrees.
That means the supplement will go from 180 - 50 = 130
Conclusion
As the acute angle gets bigger, the supplement gets smaller. This is an important idea to get clear. Bigger and Smaller or More or Less can be ugly little words, so anytime you come across them, pay attention. It will make your life in science so much easier.
