Answer:

x = 9.9

y= 11

Step-by-step explanation:

using sin(45)21 = 29.698

3x = 29.698. Divide both sides by 3

x = 9.899. Round to 9.9

In a Right triangle with 45° angles, the legs of the 90° angle are equal. Given 21,

to find the value of y, the equation is

2y -1 = 21. Add 1 to both sides

2y = 22. Divide both sides by 2

y = 11

If the two lines 2x+y=0 and y=3 are plotted on a typical xy coordinate grid, at which point will they intersect?

erastovalidia [21]

(-1.5,3) Y=3 which is up 3 and a horizontal line and 2x+y=0 can be written as y=-2x so in order to get -1.5 you have to make y=3 cause y=3 and when you do that it should look like 3/-2=-2/-2x so x=-1.5
