Q

Define System of Equations

A

A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system.

Elimination:

  1. Choose what you are going to eliminate
  2. Find the Common Multiple of you are solving
  3. Multiply both equations by the result of your common multiple
  4. Add both equations
  5. Find the other variable by plugging and solving for the variable with PEMDAS.

Q

How to apply Pythagorean Theorem?

A

https: //www.youtube.com/watch?v=CZKyThKyQ0o
1. REMEMBER THE FORMULA
2. (If you are not solving for hypotenuse you always need to subtract.)

Plug the numbers of the sides in the formula.

  1. Double it
  2. Add it (or Subtract)
  3. Square root to undo the square.
  4. Find the Square Root.

Q

How to solve all the sides of the right triangle?

A

https: //www.youtube.com/watch?v=a5WQlcFTXyk
1. If you have the angle(Theta) and one side then you can use a trig function. (sin, cos, and tan)
2. Find the appropriate trig function by using SOHCAHTOA
3. Write the Equation
4. Multiply both sides to make your variable alone.
5. Use your Scienctific Calculator.
