I dont know if u mean 5 equals 2 divided by 3x, but I got 2/15
Step-by-step explanation:
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)
32.68346376° = B
32.7° = B
When trying to round off the answer.
The shaded area is 1/6 of the area of large circle without the small ones.
you can multiple what you already got for the large circle without small ones by 1/6 and that should give you the correct answer
