X=2 is the answer hope it helps
Answer:
C
Step-by-step explanation:
A and B are wrong because 37 is prime. 31 is prime and 33 is divisible by 11 and 3 so C
Answer:
3.72769
Step-by-step explanation:
Use tangent - tan74 = 13/x
Solving for x gives you 3.72769
I'm not sure how many decimal places you need, so there are most of them
Hopefully this helps- let me know if you have any questions
You have to find the cos of angle A, so use the Pythagorean equation and trig laws to find the other side of the triangle created by angle A. 3^2 + x^2 = 5^2. x=4. This means cos(A) = 4/5). Make both cos (A) and cos (B) have equal denominators, and add. 148/185 + 60/185 = 208/185. This answer is correct, though it doesn’t appear to be any of the answers you wrote, so either those answers are wrong or you wrote something incorrectly in the problem.
