Best ResponseYou've already chosen the best response.0there's also this one: Look at triangle PQR. http://assets.openstudy.com/updates/attachments/505b3fd4e4b0cc122893ea30renee991348157849369456845882011122801pm596145625.png Segment QX is an angle bisector. Which statement must be true? A. length of segment XP = 6 inches B. length of segment XQ = 4 inches C. measure of angle XQR = measure of angle XQP = 35˚ D. measure of angle QRX = 180˚ – (90˚+ 35˚) = 180˚ – (125˚) = 55˚ I think the answer is A, is that right?

Best ResponseYou've already chosen the best response.0I don't know the first one, but I think the second one is A

Best ResponseYou've already chosen the best response.1Segment QX is an angle bisector. What do you understand by this?

Best ResponseYou've already chosen the best response.0i cut the triangle in half

Best ResponseYou've already chosen the best response.1It divides the angle into two

Best ResponseYou've already chosen the best response.0and half of 12 is 6 so that's where I get my answer...

Best ResponseYou've already chosen the best response.1It does not divide the side, it only divides the angle.

Best ResponseYou've already chosen the best response.1In case of an isosceles triangle, it divides the opposite side also.

Best ResponseYou've already chosen the best response.0well, I know its not C nor B

Renee99

Best ResponseYou've already chosen the best response.0because the measure of angle XQR is 70 not 35 right

Renee99

Best ResponseYou've already chosen the best response.0wait, looking at the wrong problem...

Best ResponseYou've already chosen the best response.0hold on im mixed up, was looking at the other problems pic... lol

Renee99

Best ResponseYou've already chosen the best response.0but yeah, the angle is 70 and not 35 isnt it?

Renee99

Best ResponseYou've already chosen the best response.0ohhh, okay, then that would make C the answer

Renee99

Best ResponseYou've already chosen the best response.0because half of 70 is 35! okay thanks so much! could u maybe help me with the first one now?

Best ResponseYou've already chosen the best response.1Which length is the radius for first question?

Renee99

Best ResponseYou've already chosen the best response.0well, its says a circumscribed circle of radius 7 inches, which kind of confuses me, but I always thought the radius was the doted line?

abdul_shabeer
 2 years ago
Best ResponseYou've already chosen the best response.1Dotted line is the radius

Renee99

Best ResponseYou've already chosen the best response.0okay, so now how do we find the measure that equals 7 inches?

abdul_shabeer

Best ResponseYou've already chosen the best response.1Why did you think the dotted line is the radius?

Renee99
 2 years ago
Best ResponseYou've already chosen the best response.0Idk, I think its a subconscious thing, I just remember that the dotted line should be the radius?

Renee99

Best ResponseYou've already chosen the best response.0I remember learning that about radius in school

Best ResponseYou've already chosen the best response.1If you want to conclude that OR is radius, then you must prove that O is the centre of the circle.

Best ResponseYou've already chosen the best response.1here's where circumcentre comes into play

Renee99

Best ResponseYou've already chosen the best response.0okay... so then would that mean that the answer is A, since we're saying it's the radius?

abdul_shabeer

Best ResponseYou've already chosen the best response.1Answer is right, but you cannot just conclude that OR is radius. The main question is that you need to prove that OR is radius

Renee99

Best ResponseYou've already chosen the best response.0okay, isn't there a formula for that, I don't have my formula sheet with me, but if I remember correctly, isn't something like 3.14(R)^2

Renee99

Best ResponseYou've already chosen the best response.0I cant remember the exact formula

abdul_shabeer

Best ResponseYou've already chosen the best response.1No need of any formula

Best ResponseYou've already chosen the best response.0where the three perpendicular bisectors meet?

abdul_shabeer

Best ResponseYou've already chosen the best response.1And it's also the centre of circle

abdul_shabeer

Best ResponseYou've already chosen the best response.1In the picture, two pependicular bisectors meet, which means the third perpendicular bisector would also meet at the same point.

abdul_shabeer
 2 years ago
Best ResponseYou've already chosen the best response.1by this you can conclude that O is the centre of circle.

abdul_shabeer

Best ResponseYou've already chosen the best response.1And OR is the radius
