Answer:
134.3
Step-by-step explanation:
In a right triangle, look at sides XW and XZ.
You now need to find XW.
In the measure of angle XZY (the one at the top) is 180 - (82 + 67) = 31 degrees.
Using the Law of Sines in triangle XYZ,
Put that into the equation for XW above...
A calculator shows that this is approximately 134.3
Answer:
Step-by-step explanation:
If ali has 23 so Raina has 7 more than Ali = 23 + 7 = 30
And trey has 4 times as much as Ali = 23 x 4 = 92
Total = 92 + 23 + 30 = 145
Answer:
C. 17.
Step-by-step explanation:
48 - 31 = 17
65 - 48 = 17
82 - 65 = 17.
Area of circle, πr² = 452.16
πr² = 452.16
r² = 452.16/π, π ≈ 3.1416
r = √(452.16/π) = √(452.16/3.1416) ≈ 11.997
Circumference = 2πr
C = 2*3.1416*11.997
C ≈ 75.38
Circumference is ≈ 75.38 m.
Hope this helps.
