use midpoint formula

  • ganeshie8
midpoint (x, y) = (x1+x2)/2 , (y1+y2)/2 18 = (x+25)/2 solve x

Let \[P(x_p,y_p)\] the other endpoint of the segment PR We have R(25,-5). Let M(18,-1) the midpoint of PR. We have : \[M\left(\frac{x_p+25}{2}\frac{y_p-5}{2}\right)\] So, we get : \[\frac{x_p+25}{2}=18\\\frac{y_p-5}{2}=-1\] hence : \[x_p=2\times18-25=11\\y_p=-1\times2+5=3\]

has an endpoint at (25, -5) and a midpoint of (18, -1). What is the value of the x-coordinate of the other endpoint? Which triangle is similar to Triangle BAM? Triangle MAC Triangle ACN Triangle BNC Triangle BAC

I posted the wrong question, sorry! Here is the real question: In the figure shown below, segment AM bisects angle BAC and NC is drawn parallel to AM. Which triangle is similar to Triangle BAM? Triangle MAC Triangle ACN Triangle BNC Triangle BAC

The image is correct, however.

thank you :) not it makes sense

BAM ~ BNC

by AA

think a bit and tell me why AA works...

Because they share an angle, right? @ganeshie8
ganeshie8
  • ganeshie8
which angle they share ?
anonymous
  • anonymous
Angle A

Okay, so I understand why the two triangle are similar. Makes sense. Can you help me with two more?

A (4, 4), B (7, 0), C (11, 3), and D (8, 7) are four points on the coordinate grid. Miranda and Pete joined the points using straight lines to draw a quadrilateral ABCD. Which statement is correct? Pete is correct because all the four sides of the quadrilateral ABCD are equal, therefore it is a rhombus. Miranda is incorrect because she has used incorrect formula to calculate the slope of the lines. Pete is incorrect because he has used incorrect formula to find the distance between the points of the segments. Miranda is correct because the slope of AB is equal to DC and slope of BC is equal to AD, therefore it’s a rhombus.
