Answer:
y intercept = 5
Step-by-step explanation:
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.

Answer:
The triangle is 50,50 80
Step-by-step explanation:
The three angles of a triangle equal 180 degrees
We only want one 80 degree angle.  That means the other two angles have to be the same, since it is an isosceles triangle.  Call the other angle x
x+x+80 = 180
2x+80 =180
Subtract 80 from each side
2x+80-80=180-80
2x =100
Divide by 2
2x/2=100/2
x = 50
Each of the other angles in the triangle would have to equal 50 degrees
The triangle is 50,50 80
 
        
             
        
        
        
Using the side of the square find the area:
Area = 30^2 = 900 square feet.
The rectangles area is the same, 900 square feet.
Let the width = X
The length would be 2X + 70
Area = length x width
X * 2x+ 70 = 900
This expands to 2x^2 * 70x = 900
Use the quadratic formula to solve for x:
-70 +/- sqrt(70^2-4*2(-900))/2*2
X = 10
Width = x = 10 feet
Length = 2x + 70 = 90 feet
