Solve the proportion 45=28x using two different methods. Explain each method

x=45/28  

Step-by-step explanation:

1.

You need to isolate the variable by dividing each side by factors that don't contain the variable. In this case, the variable would be x. Isolate x and divide it by the two factors. You have your answer.

2.

Another way you could do it is by using a proportion. You would need to set up your proportion by dividing both sides of the equation by the same term and then simplify the whole problem. You will still be left with a variable.

1 is c

2 is a

3 is a

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
