Answer:
x=1
Step-by-step explanation:
You just have to go through it thoroughly. You are probably making a small mistake somewhere.
Radius is 16in
Circumference is 2xpiXradius
So 100.5 inch
Since we know that squares have the same length on all sides, you would find the square root of 170
√170=13.03840481
rounded to the nearest tenth would be 13.1
You can check your work by multiplying 13.1 by 13.1 which equals 170.3
I try to explain the problem and give the answer, I hope this helps!
Answer:
32.7°
Step-by-step explanation:
Use the formula for law of cosines, for this question we need so solve for angle B, so use...
b² = a² + c² - 2(a)(c)Cos B
We are given a, b, and c, so plug them in...
55² = 90² + 50² - 2(90)(50)Cos B
Now simplify...
3,025 = 8100 + 2500 - (9000)Cos B
-7,575 = -(9000)Cos B (subtract 8100 and 2500 from both sides)
0.841666667 = Cos B (divide both sides by -9000)
Cos^(-1) 0.841666667 = B (use cosine inverse function on calculator)
