The area of the arrow given in the figure is 610 square cm
<h3>Area of composite figure</h3>
The given figure is made up of rectangle and triangle. The area is expressed as:
Area = Area of rectangle + area of triangle
Substitute the given parameters
Area of the arrow = (15*20) + 0.5(31 * 20)
Area of the arrow = 300 + 310
Area of the arrow = 610 square cm
Hence the area of the arrow given in the figure is 610 square cm

<span>2 cos theta = 1
Cos theta = 1/2
Inverse of cos (1/2) = 60 and 300 in degrees.
In radians we have
60 * pi/180 = 1.05
300 * pi/180 = 5.24</span>
Answer:21,628.88
Step-by-step explanation:
831.88 bi weekly x 26 weeks in a year
To solve this problem you must apply the proccedure shown below:
1. You have:
x: the positive integer that is twice another.
y: the other positive integer.
2. Therefore, you must write a system of equations, as following:
x=2y
(1/y)-/(1/x)=1/8
3. By susbtitution, you obtain:
(1/y)-/(1/2y)=1/8
y=4
x=2x4
x=8
The answer is: 8 and 4.
