The area of a circle A is 85π ft2. ∠BAC is a central angle of the circle, and m∠BAC = 36°

BlackZzzverrR [31]

As stated the area of the circle is 85π ft2. The area of the sector BAC is a portion of this full circle area. the sector is made of 2 radii and arc that has rotated by 36°.
the magnitude of the central angle in the circle is 360°
Area for 360° central angle -  85π ft2
then the area for 1° =  85π ft2/360°
the area of 36° sector =  85π ft2/360° x 36°
=  8.5π ft2

Answer: 19.6 feet

Step-by-step explanation:

Using the Pythagorean theorem,

$x^2 +(x+6)^2 =48^2\\\\x^2 +x^2 +12x+36=2304\\\\2x^2 +12x-2268=0\\\\x^2 +6x-1134=0\\\\x=\frac{-6 \pm \sqrt{6^2 -4(1)(-1134)}}{2(1)}\\\\x \approx 30.8 \text{ } (x > 0)\\\\\implies x+(x+6) \approx 67.6\\\\\therefore (x+(x+6))-48 \approx 19.6$
