The points A(-3, 2) and B(1,4) are vertices of an isosceles triangle ABC, where angle B = 90°

almond37 [142]

Answer:

Length of AB = 4.4721

Equation of line BC: y = -2x + 6

Step-by-step explanation:

To find the length of the line AB, we just need to find the distance between the points A and B.

We can find distance with the equation:

$distance = \sqrt{(x_A - x_B)^2 + (y_A - y_B)^2}$

$distance = \sqrt{(-3 - 1)^2 + (2 - 4)^2}$

$distance = 4.4721$

To find the equation of the line BC, first let's find the slope of the line AB.

This slope is given by:

$m_{AB} = \frac{ y_A - y_B }{ x_A - x_B }$

$m_{AB} = \frac{ 2 - 4 }{ -3 - 1} = \frac{1}{2}$

The line AB is perpendicular to the line BC (because mB = 90°), so the slope of line BC is:

$m_{BC} = -\frac{1}{m_{AB}} = -2$

so the line BC is:

$y = -2x + b$

To find the value of b, we can use the point B (1,4):

$4 = -2 + b$

$b = 6$

So we have:

$y = -2x + 6$

Explain why the bases of a trapezoid need to be added in the formula.<br><br><br><br> PLZZZZ HELP

Kazeer [188]

Answer:

Step-by-step explanation:

Because if you put together two trapezoids, one in a reversed position, you get a paralelogram. There the side of the parallelogram is the sum of the trapezoid bases, as in the picture.

The are of paralelogram is: A=(b+B)×h

For trapezoid, half of parallelogram:

A1=A/2=(b+B)×h/2
