work out angle x
write down the value of angle y

Answers

Answer:

x = 70° ; y = 67°

Step-by-step explanation:

1) The triangle given in the picture is an isosceles triangle. So, the base angles will be equal to each other. (People do get confused and assume that x is a base angle. But in the figure , the triangle is rotated anticlockwise. So x is not a base angle).

Using angle sum property of triangles,

[tex]x+55+55=180[/tex]

[tex]=> x + 110 = 180\\[/tex]

[tex]=>x = 180-110=70[/tex]

2) Both the lines are parallel to each other and there's a transversal intersecting both the lines at 2 specific points. So ,

y = 67° (∵ Alternative Interior Angles are equal to each other when two lines are parallel and there's a transversal intersecting them)

x + 55 + 55 = 180
x + 110 = 180
x = 70

y = 67
because theyre alternate angles

The graph represents the cost y (in dollars) to open an online gaming account and buy x games. Find the slope and the y-intercept of the line.​

Answers

Answer:

Slope = 0.1 or 1/10

Y-int. = 15

Step-by-step explanation:

We have points (0,15), (3,45), (6,75), and (9,105).

slope is rise over run, or rise/run.

So, 9-3/105-45=6/60

now, simplify 6/60.

6/60=1/10 or 0.1

We already have the y-intercept, (0,15), because that's what intercepts the y-axis.

The slope of the line is 10.

The y-intercept of the line is 15.

Locate two points on the graph, choosing points whose coordinates are integers. We will use (3, 45) and (9, 105).

Starting with the point on the left, (3, 45) going from the first point to the second point, (9, 105).

The rise on the vertical leg of the triangle = (105 - 45) = 60

The run on the horizontal leg of the triangle = (9-3) = 6

Use the slope formula.

[tex]m = \frac{rise}{run}[/tex]

[tex]m=\frac{60}{6} =10[/tex]

The slope of the line is 10.

The y-intercept of a graph is the point where the graph crosses the y-axis. (Because a function must pass the vertical line test, a function can have at most one y-intercept.

the y-intercept of the line is 15.

Therefore, The slope of the line is 10 and the y-intercept is 15.
