Answer:
4
Step-by-step explanation:
Answer:
1) The length of 
is 20.
2) The length of 
is 17.
Step-by-step explanation:
1) If 
and 
, then we can use the following proportionality ratio:
(1)
Where 
is the length of segment 
.
If 
, then the value of is:
The length of is 20.
2) If 
and 
, then we can use the following proportionality ratio:
(2)
Where is the length of segment 
.
If 
, then the value of is:
The length of is 17.
Answer:
55.2° ≤ c ≤ 55.8°
Step-by-step explanation:
We know a + b + c = 180
Let's take the smallest value of a and b and find largest value of c:
51.3 + 72.9 + c = 180
c = 55.8
Now,
Let's take the largest value of a and b and find smallest value of c:
51.5 + 73.3 + c = 180
c = 55.2
Thus, we can say, range of c is:
55.2° ≤ c ≤ 55.8°
The second reflection image would be x.
