Answer:
I would strongly recommend using a website called Desmos scientific calculator with these type of problems, not just this problem but any problem.
Step-by-step explanation:
Answer:
b = 115.4 feet
Step-by-step explanation:
b^2 = a^2 + c^2 - 2 (a)(b) x cos B
b^2 = 230^2 + 360^2 - 2(230)(360) x cos(38 degrees)
b^2 = 52,900 + 129,600 - 2(230)(360) x cos(38 degrees)
b^2 = 182,500 - 165,600 x cos(38 degrees)
b =
b = 115.4 feet
i hope this helps!! :)
The answer is D because you have to divide 812 by 25.3
