Random Math Problem 1: Trigonometry

It's time for some random math problems! Enjoy learning!

[@angeloucol8463]

Thank you po sa practice. Sinubukan ko pong sagutan before discussion, nakuha ko po using sine law para hanapin ang hyp then sct na po. Same ang na kuha.

[@jamesbryanlopez3372]

Thanks Engineer. Tatambay muna ako sa mga videos mo in preparation for board exam this coming november.

[@EngineerProfPH]

Thank you po! Goodluck sa board exam.

[@jerryrivers4256]

Salamat po, EngineerProfPH. Every step of this trig app lesson is very concise.This makes it so easy to solve a challenging problem, sir. You're not only an engineer, but an extraordinary teacher! :)

[@EngineerProfPH]

Nakaktouch naman po. Maraming salamat!

[@masterkurintisyan1995]

Reverse. Pick answer. Substitute to formula.

[@AliA-wb2tk]

use law of sines. it would be much easier.

[@antawami]

Hindi man given lahat ng angle

[@jerryjamesaves6960]

Mas mabilis sine law,

[@jerryjamesaves6960]

​@@antawamidi nga given pero note that interior of triangle is always equal to 180° kya madali lng makuha un

[@joelpabunan7820]

It is right triangle and you will only use sine law if it is oblique triangle

[@solimancedricgil6782]

Thank you engr. Nakuha ko Rin po sya using sine law

[@josephshaddix6119]

I used sine law also. It seemed more straightforward

[@niadelossantos1199]

How?

[@gela1708]

@@niadelossantos1199 (150 / sin 74) = ( z / sin 62), to get z which is the hypotenuse of A to the base of B. Then makuha na agad ang height of the A, which is h = z sin (46)

#LPT #LETpasser Oct 2022 here. Sir thanks po sa videos mo like this one. Sa mga math major ilang items May angle of elevation question. Nakatulong po ito naitama ko

[@EngineerProfPH]

Thank you and congrats po!😍🥰

[@lesterlozano4192]

It is easier to use sine law to this question

[@jeromemitchiegutierrez6465]

Sir kailan ginagamit ang degree mode and radian mode sa calculator?

[@EngineerProfPH]

Hello po! Depende po sa given na angle. Kapag nakaradian yung given set nyo po to rad yung calcu. Kapag naman po naka degrees, set nyo po to deg yung calcu. Thanks for the question!☺️❤️

THANK YOU PO....💋💢💯❤❤‍🩹🧡💛💫💦

[@leobanay6782]

dahil po sa word na from? don sa from the top of tower a, kaya naging mas mataas ang B kesa sa tower A?

[@leobanay6782]

kasi huhu bigyan nyo po ako ng hustisya nalilito ako,, kasi sa problem is elevation ng top of tower B eh? meaning po ang observer ay yong B? so dapat mas mataas sa kanya yong isang building?

[@EngineerProfPH]

Hi! Yung key phrase po is "the angle of elevation of the top of tower B from the top of tower A" meaning yung elevation ay galing sa tower A papunta sa tower B. Ibig sabihin ay mas mataas si tower B kasi papunta sa kanya ang elevation galing sa A.

[@EngineerProfPH]

"Angle of elevation from A to top of B" so therefore mas mataas si tower B

[@leobanay6782]

yon po nabigyan na po ng hustisya, hehe,,

Anong gamit nyo Po sa pag draw Ng mga equation?

Hi! Wacom pen tablet po.

[@williamjonathanangiii9105]

Good day engineer may one question lang po ako paano po naging (150-h) tan46°/h?

[@EngineerProfPH]

Ah okay po, kapag fraction po kasi ung denominator mo, ung denominator ng fraction na un ay pwede pong ilagay sa taas at mamultiply sa numerator.
So; (150-h)/ (h/tan46°)
multiply ka ng tan46° sa both numerator and denominator to simplify. This gives you;
(150-h)(tan 46°)/ (h/tan46°)(tan 46°)
= (150-h)(tan 46°)/ h
