HELP?

OpenStudy (rz172):

Is it 141?

OpenStudy (rz172):

@princeharryyy

OpenStudy (princeharryyy):

x+y =z

OpenStudy (rz172):

114?

OpenStudy (princeharryyy):

x = 180-73-42 = 65

OpenStudy (princeharryyy):

y= 180-131 = 59

OpenStudy (princeharryyy):

z = 59+65 = 124. check the calculations.

OpenStudy (rz172):

I thought; x = 65 y= 49 z = 49 + 65

OpenStudy (princeharryyy):

ohh yeah, actually I'm doing st. so, not paying a lot of attention on calculation. u r right.

OpenStudy (rz172):

So it is 114?

OpenStudy (princeharryyy):

yeah.

OpenStudy (princeharryyy):

method is same. LOL

OpenStudy (princeharryyy):

180-131 =49. (sorry, correction)

OpenStudy (princeharryyy):

it is 114. :)

OpenStudy (rz172):

Which os these is an impossible construction? A. bisect an angle B. trisect an angle C. quadrisect a segment D. copy an angle

OpenStudy (princeharryyy):

i haven't heard copying an angle. LOL

OpenStudy (rz172):

I think it's B?

OpenStudy (princeharryyy):

u can trisect angle, no big deal.

OpenStudy (rz172):

Is this true?

OpenStudy (princeharryyy):

let angle be 90 divide using 3 lines making each 90/3 = 30 deg

OpenStudy (princeharryyy):

https://en.wikipedia.org/wiki/Angle_trisection

OpenStudy (princeharryyy):

yes, that is possible. making a hexagon in a circle using compass.

OpenStudy (rz172):

How about?

OpenStudy (princeharryyy):

16

OpenStudy (rz172):

Is this 5?

OpenStudy (princeharryyy):

yes

OpenStudy (osprey):

Below MAY be right ... x=65 (angles of a triangle) y=49 (angles on a straight line) angle on the same straight line as z = 82 z=98 (angles on a straight line add up to 180)

OpenStudy (rz172):

How do I find this?

OpenStudy (princeharryyy):

nah! @osprey. that's incorrect. 114 is right.
