The answer is 3.9 x 10^-5
Answer:
A ≈ 9.0 ft²
Step-by-step explanation:
70° = 7π/18 radians
Area of the arc section
A = ½(7π/18)8² = 12⁴/₉π ft² = 39.09537 ft²
As the triangle is isosceles, the other two angles are (180 - 70) / 2 = 55°
law of sines 8 / sin55 = L / sin 70 L = 9.17722
so the triangle height = √(8² - (9.17722/2)²) = 6.55321
Area of triangle ½(6.55321)(9.17722) = 30.07016
Area = 39.09537 - 30.07016 = 9.025211 ≈ 9.0 ft²
2(2d+4)=-3(d+2)
4d+8=-3d-6
4d+3d=-6-8
7d=-14
d=-14/7
d=-2

Answer:
126.5
Step-by-step explanation:
Divide the shape into two, so you have a triangle and a rectangle.
Area of Rectangle:
A = bh
= (11)(8)
= 88
Area of Triangle:
A = 1/2bh
= 1/2(11)(7)
= 38.5
Add the two areas and the answer is 126.5
