Great! Thank you.
You're welcome! Best of luck on your exam!
9:42 please could you elaborate more on why the alternate angles aren't equal to each other or is it because the two traingles are inside acircle
This definitely won't be on your exam. This is called Congruent Inscribed Angles Theorem. Feel free to watch a video covering it:

I hope this helps!
Great video. Thank you
Could explain the hourglass triangles angle similarity. For instance in 2:03 you said angle A = Angle C, but in 1:07:50 angle A isn’t equal to angle Q.
I mainly get confused when to if the parallel lines are equal or not.
Hi Rotimi! Could you be more specific? You can't call an angle "Angle Q" or "Angle A" when there are multiple angles utilizing that vertex. You have to use 3 letters to refer to an angle (like in the problem statement how it says angle AQB). I don't know what you are asking me.
@@Tutorllini Oh my bad.
Could explain why the two angles in the similar triangles question (hourglass-shaped) are joined together; these angles are equal to each other in the first question but not the second question. For instance, in 2:03 you said angle DAE = Angle BCE, but in 1:07:50 angle PAQ isn’t equal to angle AQB.
I usually get confused about whether they are equal due to the parallel lines or alternate.
@@rotimifr Hi! It seems like you don't understand what alternate interior angles are. It helps to draw a little "Z" shape with your finger to spot them. Watch this video - it has a little animation that shows the Z figure abot halfway thru.

I hope this helps!
@@Tutorllini thank you very much. Your math videos on channel made me more confindent for my exam tomorrow. You and your channel deserve more love. I really appreciate it your help. :-)
@@rotimifr You're welcome Rotimi! You coming to the after exam livestream tomorrow?
1:04:26 shouldn't we take the cos-1 to figure out the angle?
No? The question is not asking you for x - it is asking for you cos x. You are going in circles. Also, Maria, just keep in mind that inverse trig functions are not covered in the DSAT syllabus :) Hope this helps!
@@TutorlliniOpsss my bad! I just read the question again, and yeah it was asking about cosx, not x. 😅
1:01:34 how did youu get 10 for AC?
Hi Reem! SIN tells you those sides are in the ratio of 5 to 13. BUT the figure says AB is 26. So they must ACTUALLY be 10 to 26 (to be in the 5 to 13 ratio). I hope this helps!
Thanks your vid are so helpful.
Can I solve all the sat math exercises only with desmos?
No
Sir do u have all the formula needed for maths SAT especially for algebra and trigonometry?
No. This does not have all of them either but maybe this will help you:

bro Im cooked my test is at 7:45 i have most if not all of my demos forumals down but im stuggliong on trigs man JKLfind the soluton to JKL to sinKL
trying to speedrun trignometry
how many more guides are there?
Videos based on the Official Guide book? This is it. There are 4 chapters, one for each of the domains covered on the DSAT Math exam.
can you do the same for english? if not, do you know anyone who does something like this for english?@@Tutorllini
@@aravjee8982 No sorry!
7:00 arent the sum of interior angles (n-2) 180? whyd you put 360
Did you keep watching? I fixed it less than 2 minutes after that timestamp.
@@Tutorllini yes thank you i commented before I continued
@@alijaafar1753 No worries! When is your exam?
@@Tutorllini I did it on november a few days ago but i performed bad in geometry and planning to repeat in december.
@@alijaafar1753 Nice! Make sure you drop by the Community Tab and let me know how it goes.

I'll also be hosting a livestream this Friday if you want to stop by!
