The height of the isosceles triangle is twice the length of its base what are the coordinates of the undefined vertex ?
gayaneshka [121]

<u>Answer-</u>

<em>The coordinate of the vertex is </em><em>(7, 12)</em>

<u>Solution-</u>

The coordinates of two end points of the base are, (4, 0), (10, 0)

As the triangle is an isosceles triangle, so the other vertex will be on the perpendicular bisector of the base.

The mid-point of the base is,

=(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2})

=(\dfrac{4+10}{2},\ \dfrac{0+0}{2})

=(\dfrac{14}{2},\ \dfrac{0}{2})

=(7,\ 0)

As given that the length of the height is twice that of the base,

Length of the base is,

=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

=\sqrt{(10-4)^2+(0-0)^2}

=\sqrt{(6)^2}

=6

Length of the height will be =6\times 2=12

So the vertex is 12 units vertically up from the mid-point (7, 0). Then the coordinate of the point will be (7, 12)

Help me with this problem
ryzh [129]

Answer:

Looking at the given points we know that it is going to be a triangle because it only have 3 points.  Therefore the figure is a triangle and the area formula would be A=\frac{1}{2}*b*h.

You can look at the attached graph and what we see is that our height of the triangle is from y=-3 to y=4 which means that our height is 7 units high.  We can also see that our base starts at x=-4 and ends at x=4 making us have a base of 8 units.

<u>We then plug in the values and solve</u>

A = \frac{1}{2}*7\ units * 8\ units

A = \frac{1}{2}*56\ units^2

A = 28\ units^2

Therefore, the area of our triangle is 28\ units^2

Hope this helps!  Let me know if you have any questions
