We are trying to find the average speed of the plane, which is mph, or 
. Using proportions, we can find the average speed of the plane in mph:
- Use the information from the problem to create a proportion. Remember that we are looking for mph, so we will call that
.
- Multiply the entire equation by
- Divide both sides of the equation by
to clear both sides of the mile unit
The average speed of the plane is 300 mph.
The area of triangle ABC is the amount of space on the triangle
The area of the triangle is 54.84 square units
<h3>How to determine the area of triangle ABC</h3>
Start by drawing the triangle (see attachment)
Next, calculate the measure of angle B using the following tangent ratio
This gives
Take the arc tan of both sides
Multiply by 2
Next, calculate the length of side AD using the following equation
This gives
The area of the triangle is then calculated as:
This gives
Hence, the area of the triangle is 54.84 square units

Answer:
m is equals to 49 degree + 31 degree so which means it's 80°
Answer: just turn them into decimals and use a calculator then turn them back into fractions in simplified form
Step-by-step explanation:
It takes 45 seconds. the easiest way to do these is to use a graphic calculator and replace the variables with x and y, for example, this equation would become -5x^2+30x, and if you don't have access to a graphing calculator, you can always use desmos online.
