Answer:

54 degrees

Step-by-step explanation:

Every side of a regular pentagon is same.

So we have an isosceles triangle. The correspond angle of y, must equal to y (degree) too.

Also, every inner angle of a regular pentagon is 360/5=72. So we can calculate angle y, by the equation y+y+72=180.

y=54

Graph the systems of equations. {2x+y=8 −x+2y=6 Use the Line tool to graph the lines.

Nitella [24]

Answer:

See attachment

Step-by-step explanation:

We want to graph the system

2x+y=8

-x+2y=6

Let us rewrite the lines in slope intercept form:

y=-2x+8

$y=\frac{1}{2}x+3$

The first line has a slope of -2 and a y-intercept of 8

The second line has a slope of 1/2 and a y-intercept of 3

We can no graph the lines as shown in the attachment.
