Sir bahut Kam aaya. Thank you 😊
It is so easy
Helpful 😊
14:32
Sir iske ans less than 45 aayega😊
Thank you so much sir i had really struggled to do the 12 sum but by seeing your videos sir ihave solved within a minute thank you so much magnet brains 🧠
Sir because of you I got 79.5 in maths I am very happy and because of magnet brains I got 99.9%i am very happy now I am in class 8 😊😊😊❤❤❤😂😂😂🎉🎉🎉
Sir...i wanted to ask you that in 16:35 the question says "an angle is GREATER THAN 45° " which means that it's complementary angle should be less but u said it's "equal to 45° "...what is the real answer?
Less than 45°
Less than 45°
Less than 45
Yess less than
Yess
Guys, please pay attention here Question 8 is explained wrongly I mean think about it the question said that if the angle is more than 45 degrees so the compliment will be less than 45 more than 45, or equal to 45, for example, we take 46 degrees ( ATQ we had to take more than 45 so 46) and two complimentary angles make 90 degrees so if we want to take the complimentary it would be less than 45 and they're saying that it should be equal to 45. WE NEED JUSTICE

Just for the wishes and meditation I will be able t shi is the best deal in my 2car history c independently from my house or the day of my gift kay chalu and I am not available to be implemented to make the same work in the same way that time 😂and u can I have a problem aahe and 😂😅😂 i will 😂😅😂 and it will 😂

Sir your all concepts are clear to me,u re the best maths teacher
Sir
Thanks for everything sir❤❤
Let theta equal to 50 degree then its complementary angle will be. 90'+50'=40' less than 45'
Aapka 8 wala question Shayad wrong hai Kyunki Mein solve Kiya To yah answer A raha tha
Thank you for your comment! You are correct that the complementary angle of 50 degrees is 40 degrees.
You don't need to say thank you. You a are teacher we are a student

THANK U SIR AGAIN AND AGAIN
Sir you are best teacher in the world and now tomorrow is my exam and i don't know anything in exam i watched your video and thnx sir for easy my math 😊
Thank you sir tomorrow is my test I really needed this
Sir in the 8th question it is written that *an angle is greater than 45°* so the answer will be less than 45°
You are right
Yes

Thank you so much sir You are best teacher in world😍😍
Yes,
Sir in the 8th question the answer will be less than 45 degree because the 8th question says that An angle is greater than 45 degree and which is equal to its complementary Example Greater than 45 degree so i will take 46 +44=90 degree and 44 degree is less than 45 degree so the answer is less than 45 degreeg and in the ncrt book answer is less than 45 degree
You are right
I think it should be greater than or equal to 45°, so that the answer would be perfect which is less than or equal to 45°
You are right
It's given in question that p > 45°
Adding q > on b/s
90°>45°+q
90°-45°>q
Q
Hm

Thank you thank you thank you so much sir tomorrow is my periodic test first and I am allready prepare 🙏❤️
sir question number 8 of exercise 5.1 is wrong it has asked that the number is greater than 45 ,so means it can be 60 degree also 54 degree also ,so logically the other complementary angle can be less than 45 degree.
Right?
Yes

Yes

Sir as u explained in question 5 An angle is greater than 45° then if the other one will be 45° it wouldnt be a complementary angle .
Answer of q8 will be less than coz the other angle is greater 🙂.
This was the ques of many students so I explained 🙂
Nice 👍 sir you are best teacher in world😀😀
No you are wrong
When when a digit decreasing then another digit increase in the same order example
45 + 45 when it decrease
44 + 46
sir, in question no.14 (2) there is one more pair i think so and that is=EOD,DOC....................EDIT: no no sir they are not complementary.....thanks

In 8th question the angle is less than 45 degree because the question is an angle is greater than 45 degree
SIR THANKS ALOT BECAUSE YOU ARE THE BIGGEST GLORY OF MATHS THANKU FOR EXPLANIATION BECAUSE TOMMAROW IS MAY EXAMS
Watching ur videos from 1 year, have improved my grades a lot because of u Abhishek sir, TYSM! Waiting forward for more videos from u ❤
Thank you so much for your kind words! I'm so happy to hear that our videos have helped you improve your grades. We'll continue to make new videos and I can't wait to see your continued success!
sir if the question is. find the angle which is equal to its compliment can i write
100+80=180???
180 compliment thodi hota Ha, 90 compliment hota hai aur 180 supplement hota hai.
180° is not complementary angle it is supplementary angle and if the question will find the angle which is equal to its supplement so the answer will be always 90°+90° because 90° is equal to its supplement and 90°+90°=180° is correct and 100° is not equal to its supplement 80° because both numbers are different it should be equal
Sir you are the best teacher among the world you teach very well.
THANKS for teaching.
