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

15.04 degrees or answer A is correct.


The Law of Sines is the relationship between the sides and angles of non-right (oblique) triangles . Simply, it states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in a given triangle. The formula for it is A=b•sin a/sin b.


You can transform the law of sines formulas to solve some problems of triangulation (solving a triangle). You can use them to find:

The remaining sides of a triangle, knowing two angles and one side.
The third side of a triangle, knowing two sides and one of the non-enclosed angles. In some cases (ambiguous cases) there may be two solutions to the same triangle. If the following conditions are fulfilled, your triangle may be an ambiguous case:
You only know the angle α and sides a and c;
Angle α is acute (α < 90°);
a is shorter than c (a < c);
a is longer than the altitude h from angle β, where h = c * sin(α) (a > c * sin(α)).

I hate useless complicated math lol ;)

The formula Upper V equals LWH is used to find the volume of a box. If the length of a box is increased 4 times​, the width is i
marysya [2.9K]

Answer:

the volume of the box increases 48 times compared to the 1st one.

Step-by-step explanation:

Volume of the box (1) = LWH

  • length of a box is increased 4 time = 4L
  • width is increased 4 times​ = 4W
  • the height is tripled​ = 3H

=> The new volume of the box = 4L * 4W * 3H = 48LWH  

So the volume of the box increases 48 times compared to the 1st one.

What is the percent decrease when the balance in a bank account goes from $300 to $60?
