Step-by-step explanation:
Answer:
The area and perimeter of the given shaded figure are respectively 33.12 unit² and 20.56 units.
Area and perimeter-based problem:
What information do we have?
Radius of semi-circle = 8 / 2 = 4 unit
Length of remain Rectangle = 8 unit
Width of remain Rectangle = 2 unit
Perimeter of shaded figure = πr + (l + 2b)
Perimeter of shaded figure = (3.14)(4) + [4 + (2)(2)]
Perimeter of shaded figure = 12.56 + 4 + 4
Perimeter of shaded figure = 20.56 units
Area of shaded figure = πr²/2 + lb/2
Area of shaded figure = (3.14)(4)²/2 + (8)(2)/2
Area of shaded figure = (3.14)(8) + 8
Area of shaded figure = 25.12 + 8
Area of shaded figure = 33.12 unit²
Below
● cos O = 2/3
We khow that:
● cos^2(O) + sin^2(O) =1
So : sin^2 (O)= 1-cos^2(O)
● sin^2(O) = 1 -(2/3)^2 = 1-4/9 = 9/9-4/9 = 5/9
● sin O = √(5)/3 or sin O = -√(5)/3
So we deduce that tan O will have two values since we don't khow the size of O.

●Tan (O) = sin(O)/cos(O)
● tan (O) = (√(5)/3)÷(2/3) or tan(O) = (-√(5)/3)÷(2/3)
● tan (O) = √(5)/2 or tan(O) = -√(5)/2

1¾ miles/(2⅓ minutes) = (7/4 miles)/(7/3 minutes) = ¾ mile/minute
21 minutes × ¾ mile/minute = 15.75 miles
60 minutes × ¾ mile/minute = 45 miles
