kolezko [41]
The formula for the area of a sector in radians is  A= \frac{1}{2}r^2 \theta,  where theta is the angle in radians.  For us, the formula looks like this:   A= \frac{1}{2}(9)^2* \frac{3 \pi }{5}.  Doing all the multiplication on that gives us  A= \frac{243 \pi }{10}.  Multiplying in pi and rounding to the nearest tenth gives us an area of 76.3 meters squared.  You can use the formula for the area of a sector with the angle in degrees as well.  Just replace the 360 degrees with 2pi and it works the exact same way.

What is the value of x? Round to the nearest tenth(1 decimal place)​
liraira [26]

Answer:

x ≈ 15.0 ft

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Trigonometry</u>

  • tan∅ = opposite over adjacent

Step-by-step explanation:

<u>Step 1: Define</u>

Angle = 28°

Opposite leg of angle = 8 ft

Adjacent leg of angle = x ft

<u>Step 2: Find </u><em><u>x</u></em>

  1. Substitute:                                        tan28° = 8/x
  2. Multiply <em>x </em>on both sides:                 xtan28° = 8
  3. Divide tan28° on both sides:          x = 8/tan28°
  4. Evaluate:                                          x = 15.0458
  5. Round:                                              x ≈ 15.0 ft
