sustiute 1 and -1 to x y=tan^3(x) you get postive and negative values , odd function
y=1/sec^3 x is even and same goes on
The area of the composite figure = 10,874.1 sq. m.
The perimeter of the composite figure = 406.9 m
<h3>What is the Area and Perimeter of a Rectangle and Circle?</h3>
Perimeter of a rectangle = 2(length + width)
Area of a rectangle = length × width
Perimeter of a circle = 2πr
Area of a circle = πr²
<h3>
What is Area of the
composite figure?</h3>
The figure is made up of two semicircles (1 full circle) and a rectangle.
Area of the composite figure = area of circle + area of rectangle
= πr² + length × width
r = 36.5 + 1.2 = 37.7 m
length = 85.0 m
width = 2(36.5) + 2(1.2) = 75.4 m
Substitute
Area of the composite figure = π(37.7)² + 85.0 × 75.4 = 10,874.1 sq. m.
<h3>
What is Perimeter of the
Composite Figure?</h3>
Perimeter of the composite figure = perimeter of circle + 2(length of the rectangle)
= 2πr + 2(L)
Plug in the values
= 2π(37.7) + 2(85.0)
Perimeter of the composite figure = 406.9 m

Calculate the difference : 
Reduce the fraction : -
Solution : -
3x + 5x + 7x = 180
15x = 180
x = 180/15
x = 12
Largest angle = 7x = 7*12 = 84°
