Construct a circle with a radius of 8cm, and draw an equilateral triangle inside it. Make sure the length of each side measures

Ipatiy [6.2K]

Answer:

Diagram 1

Draw a circle with a radius of 8 cm, ensuring you have clearly marked the center point (black circle with center C1)

Add a point on the circumference of the circle (point C2)

Draw a second circle of radius 8cm with point C2 as its center (red circle with center C2).

Diagram 2

The red circle intersects the black circle at two points (D and E).

Connect these 2 points of intersection with a line segment.

Diagram 3

Draw a third circle with center D and radius DE (shown in blue)

This circle intersects the black circle at point F.

Diagram 4

Draw 2 line segments to connect points D and E with point F - this is your equilateral triangle inside the circle!

Points (0,6) and (-4,y) lie on the line with a slope of 5

Anna [14]

For this case we have that by definition, the slope of the line is given by:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}$

According to the statement we have:

$(x_ {1}, y_ {1}) :( 0,6)\\(x_ {2}, y_ {2}): (- 4, y_{2})\\m = 5$

Substituting the values:

$5 = \frac {y_ {2} -6} {- 4-0}\\5 = \frac {y_ {2} -6} {- 4}\\5 * -4 = y_ {2} -6\\-20 = y_ {2} -6\\-20 + 6 = y_ {2}\\y_ {2} = - 14$

Thus, the value of $y_ {2} = - 14$

Answer:

$y_ {2} = - 14$
