Answer:
x = 5 
Step-by-step explanation:
Hi there!
So, to answer this problem, I'll use the reverse method.
31 - 4 = 27,
So how many times, can 5 go into 27?
The closest factor of 5 to 27 is 25.
5 can go in to 27, 5 times.
Continuing on, there is a 2 left over, so the answer to your question is
x = 5 
5 · 5
- 4 = 31
Let me know if I am incorrect and I will attempt to find the right answer for you.

Answer:
21.8° (22° to the nearest degree)
Step-by-step explanation:
Using cosine law:
a² = b² + c² - 2bc(cosA)
3² = 5² + 7² - 2(5)(7)cosA
cosA = 13/14
A = 21.7867893
Approximately angle: 22°
