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

Answer:
a=6.9
Step-by-step explanation:
Since you know that C is a right angle, you can use the Law of Sines to find a. The first step is to find the size of the angle A, which is 180-74-90=16. Now, you set up a ratio that involves 3 knowns and one unknown to get 
, which after cross multiplying yields

Answer:
The sum of the values of Annikas 4 cards is -16
So you want to make one of the equations equal to one of the placeholders exg y=x+3
so we have
x+y=2 and
-2x+y=2
I chose to make -2x+y=2 equal to y so
-2x+y=2
add 2x to both sides
y=2+2x
subsitute 2+2x for y in x+y=2
x+2+2x=2
add like terms
3x+2=2
subtract 2 from both sides
3x=0
x=0
subsitute x=0 in x+y=2
0+y=2
y=2
x=0
y=2
