Plane Geometry: Finding the missing angles

[@profrobbob]

Awesome! Very well explained🤓 I like the translations you are adding.

Thank you prof.

[@irenengonjeng]

Sir do you really exist????.....oh lord your explanations are juste waaaouououh

[@DaliaJustine-ll7ps]

❤ math

[@DotRabbit]

I did it like this, I drew a line parallel and wrote the other angles i got as z and y respectively. Through this i got x+y = 123 eq 1 and x+z = 105 eq2 .And from the straight line line properties i got x+y+z = 180 . Then, i added eq 1 and 2. I got x+y+z+x = 228
Substitute x+y+z= 180 you get x+180=228 you get x = 228-180 = 48.
For the second one we can draw a radius OA. You get OA = OB= OC .
Then, those two are isosceles triangle formed. Angle OBA = OAB = 30. Then Angle OAC = 20. Since isosceles triangle property states two adjacent angles are equal when their corresponding sides are equal. OAC= OCA = 20.

Well done sir ☺️
I never understood the circle theorem when I was at school but this your explanation have made me understood
God richly bless you 🙏🙏

Thank you

You are the best in mathematics I understand ur maths very well

[@tambuwalmathsclass]

[@seriousgamer05pami79]

This has helped me understand angles and using parallel line to my advantage and sir can I say you have a very good eye for finding different ways to solve problems 0:53 and 1:34

[@isaacvaye4961]

You make me to understand this other type of geometry thank you very much

[@tambuwalmathsclass]

🙏🙏

[@我是我-k2r]

Case 1: 105+123-180= 48. In 2nd case. OA=OB (Radius) so angle BAO = 30 degree AOC=20 degree. OA = OC so angle ACO=20 degree.

[@Redeemer-ti7wr]

[@zakariyeidiriz7514]

Question two sir
Just you can do very shortcut way.
First find angle of centre is 100 right
Then 360_100
Equal 260
So you can found y by quataleral
By adding of 50+30+260+y= 360
Then like terms y= 20😂
