Answer:
71°
Step-by-step explanation:
In order to be able to solve this problem, we must assume the relation between lines "a" and "b" is that they are parallel.
If a║b, then ∠1 and ∠2 are corresponding, hence congruent.
m∠1 = m∠2 = 71°
Answer:

The value of a is 9 and b is -8
Step-by-step explanation:

We need to find two numbers that add up or subtract off to 1.
Then we also use the same two numbers that multiply and get -72.
Let's see:-
- 9 and -8 seem like correct values.
Because 9+(-8) is 9-8 = 1
And 9(-8) is -72.
Therefore:

The value of a is 9 and the value of b is -8 according to form of (x+a)(x+b)
Answer:
The distance is 9.21954445... or just 9.22
You're doing it exactly right! Keep on going! :)
