Answer:
The slopes are m=3 and m=-2
There is only one solution
Step-by-step explanation:
That would be B because 65 < 40 + 30
3. is an obtuse angle and has a measure of 165 degrees
4. is an acute angle and has a measure of 55
Answer:

Step-by-step explanation:
Given:
S = 52.5°
s = QR = 7
Q = 80°
q = RS = ?
Required:
Equation that could be used to find the length of RS
Solution:
We would need the law of Sines which is given as:

Applying the Law of Sines, we would have the following equation:

Plug in the values

Therefore, the equation that can be used to determine the length of RS is
