I know its one of the congruent ones, as one is for sure a 90 degree angle, on top of an 180 degree angle, which by law of supplementary angles makes the other one 90 degrees. Not sure on the postulate, maybe someone else can help with that.

ELEN [110]

Step-by-step explanation:

coordinate point of B(2,5)

and coordinate point ofC(3,1)

Distance of BC

$\sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$

$= \sqrt{ {(3 - 2)}^{2} + {(1 - 5)}^{2} }$

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

$= \sqrt{1 + 16} = \sqrt{17} = 4.12 = 4.1$

A. The sum of Andre and Brandon scores on a math quiz is 180. Andres score is 2 times more than 30 less than Brandon score. Find

pantera1 [17]

A)

a+b=180 and a=2(b-30) using this in the first equation gives you:

2(b-30)+b=180

2b-60+b=180

3b-60=180

3b=240

b=80 so a=100

Andre's score was 100 and Brandon's score was 80.

b)

100x-200>50x-75 subtract 50x from both sides

50x-200>-75 add 200 to both sides

50x>125 divide both sides by 50

x>2.5

If XD = 2X – 6 and XV = 3x – 6 and WY and XV bisect at D, what is XV?

frez [133]

The diagonal WY bisects the diagonal XV at point D, which means that XV is divided into two equal line segments XD and XV.

$XD=XV$

Replace the equation above with the given expressions for both line segments:

XD= 2x-6

XV= 3x-6

$2x-6=3x-6$

$undefined$
