Yeah it was 69.2. But I love how clear this was explained. Love these Vivid Math videos.

[VividMath]

Your absolutely correct! I used two decimal places and rounded it up to 69.3. Good Noticing. Thanks :D

i have this questions from my maths teacher, it said "A girl standing at B is flying kite.
the kite, K is vertically above A
the string, BK attached to the kite is 24 to the horizontal.
calculate the angle of elevation of the kite when viewed from C. "

can you help me sir with this problem? thankyou.

my teacher taught us this in class and overcomplicated it so much wow this really isnt that difficult

[Dark_Messiah-D]

X actually equals "69.2" not "69.3". A minor mistake in the subtraction, but otherwise, the explanation was clear, helpful.. just absolutely beautiful :D

[bongekiledlamini]

Your videos are really helpful sir. Thank you 🥺🌻

Everyone always search for this when exams are close

What if opposite side is missing? How do we solve it?

[SimplyAvalon]

How would you find the height if 60 was unknown and you had the long side's length and the two angles??

[Randomthing]

What if you’re given distance between points but no height

[Marxismeva]

112.8 - 43.6 = 69.2 not 69.3

Your videos are always very well explained.

But what if im not given the 60?. In a problem im trying to solve im actually given the value of X and im asked to find the 60.

[geraldnatividad]

yes it should be 69.2  because ive check it by adding x to b to give an exact equal of 112.8> a=112.8 otherwise if it is 69.3 it will become 112.9. but still thanks though, ;)
