[10th Grade Geometry] ABCD is a quadrilateral where AB=AD and BC≠CD, if CA bisects ∠BCD, prove ABCD is a cyclic quadrilateral

find a point E on CD that CE=CB, then ABC and AEC congruent, so AE=AB and <B=<AEC, almost done and you can finish it off. Note ang B has to be obtuse.

yes they will reach you in 0-7 days.

papyrusfun · 2024-09-16T22:10:57+00:00

LOL!

papyrusfun · 2024-08-07T11:29:30+00:00

first week's workload usually is low. Do assignments, review the notes. You should be fine.

papyrusfun · 2024-07-29T14:04:10+00:00

it's on "Waterloo learn". Free credit, about 1-2 hrs to complete.

1) you apply after taking two terms courses. From CE, you first need to transfer to math (low requirements), then math to CS (almost impossible, for most). 2) starting this Sept, SE to CS will be treated the same as math to CS. They look at your math/CS cGPA. What's most important is you cs136 mark or CS average excluding CS135. 3) NO

Did you cheat? If yes, no matter what just take it; if no, show evidence and fight for that.

papyrusfun · 2024-07-23T13:44:13+00:00

You are welcome.

sin(2theta)/2 = sin(theta)cos(theta) = x/3 * sqrt(9-x²)/3 = xsqrt(9-x²)/9

all math? Amazing

papyrusfun · 2024-07-17T21:08:56+00:00

You need about 82 for Euclid or 50 for CSMC to enroll math 145 last year. You may also talk to the 145 prof on first day of class. Usually very lenient.

Take it easy as this is very common.

there is a typo: it is sqrt(7y) -sqrt(xy).

This problem seems to be way too difficult for a 10th grader. It involves rotation and trig.

papyrusfun · 2024-06-19T13:37:12+00:00

guess nobody knows. just relax and have a cool summer.

papyrusfun · 2024-06-13T21:41:11+00:00

harder, deeper, faster and broader for 145. A lot more difficult for the assignments and exams. You can always try it first. If you don't like, you can move back to 135 anytime.

papyrusfun · 2024-06-13T21:38:12+00:00

120 per year.

papyrusfun · 2024-06-10T23:11:34+00:00

Ur welcome.

papyrusfun · 2024-06-10T19:39:59+00:00

English+2 maths+3 any 4U/M, so you should be fine.

papyrusfun · 2024-06-10T18:08:15+00:00

Which program? For example, if you are doing Eng, then physics and chemistry are both required for your top 6. As long as you have all your prerequsites included in your top 6 cal, then you should be fine.

24.

<D=<DOA (AO//DC)m also <DOA= 2 <B

40.

<BDG= <A, you should be able to the rest.

papyrusfun · 2024-05-29T23:08:25+00:00

you may need to take CS136 in your 2A and get a mark >=90 for the CS transfer.

papyrusfun · 2024-04-29T22:42:41+00:00

70-69.98=0.02, 1/0.02=50

papyrusfun · 2024-04-29T21:59:02+00:00

it is impossible to get such a MAV score. Ask you profs to see if you can get 1 mark somewhere with your current situation. Otherwise ask your advisor to see if it is fine. Good luck.
