The sum of two numbers is 28. the first number, x, is three times the second number, y.

which system of equations can be used to find the two numbers?

Step-by-step explanation:

Let x and y represent our required numbers.

We have been given that the sum of two numbers is 28. We can represent this information in an equation as:

We are also told that the first number, x, is three times the second number, y. We can represent this information in an equation as:

Therefore, our required system of equation would be:

probably .5

i can on others if necessary.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
