This equation can have a number of solutions. Typically when solving a two-variable equation, you are looking for the slope intercept form of the line. In this case that is:

y = 3x - 1

Answer:

The answer to your question is VW = 2.2

Step-by-step explanation:

Data

angle = 63°

hypotenuse = ?

adjacent side = 1

Process

To solve this problem use trigonometric functions, the trigonometric function that relates the adjacent side and the hypotenuse is cosine.

        cos α = \frac{adjacent side}{hypotenuse}

solve for hypotenuse

        hypotenuse = \frac{adjacent side}{cos \alpha}

Substitution

        hypotenuse = \frac{1}{cos 63}

Simplification

         hypotenuse = \frac{1}{0.45}

Result

         hypotenuse = 2.2

Select the best method of finding an accurate solution to a system of linear equations
Flura [38]

The best method for solving the system of linear equation is by the use of algebraic methods.

The system of linear equations can be solved by using the method of simultaneous equations. Here we are given two equations and two unknown variables. We can solve the same by eliminating one of the variables and then either adding or subtracting, find the value of the other variable. Once we know the value of one variable, then we can substitute its value in any one given equation and find the second variable. This method is said to be accurate and does not involve any error.

Hence answer is : USE ALGEBRAIC METHODS
