analog plank im so done my ass is not passing gcses

you’re very close!

#

what can you use to find h in the diagram you drew?

analog plank Aug 10, 2023, 2:33 AM

#

nothing

#

im going to dig my eyeballs out

empty quartz Aug 10, 2023, 2:33 AM

#

it’s not a trig function

analog plank Aug 10, 2023, 2:33 AM

#

wjaat

empty quartz Aug 10, 2023, 2:33 AM

#

you have two side lengths of a right triangle, you use….

analog plank Aug 10, 2023, 2:34 AM

#

pythorcuems

#

the

empty quartz Aug 10, 2023, 2:34 AM

#

yes!

analog plank Aug 10, 2023, 2:34 AM

#

yeah

#

what do i even get from finding H though i need the angle not lenght

empty quartz Aug 10, 2023, 2:35 AM

#

do you know inverse trig functions

analog plank Aug 10, 2023, 2:36 AM

#

yeah

empty quartz Aug 10, 2023, 2:36 AM

#

what do they do

analog plank Aug 10, 2023, 2:36 AM

#

oh

#

ok

#

yeah i get it now

#

thanks

#

im goimg to hangmyself aftet his

empty quartz Aug 10, 2023, 2:37 AM

#

no no you’re doing fine!

analog plank Aug 10, 2023, 2:37 AM

#

im so done with math

#

i wake up 8 am every thursday just for math tution even though its my summer break

#

and gcses is in like what 100 days?

empty quartz Aug 10, 2023, 2:38 AM

#

most questions youll see on your exams will basically be the same thing but with different numbers

#

so once you solve like this question others will make more sense

analog plank Aug 10, 2023, 2:39 AM

#

but

#

im so bad at math

#

i also dont know how to do this

empty quartz Aug 10, 2023, 2:39 AM

#

nono you figured it out

#

just overlooked like one tiny thing

empty quartz Aug 10, 2023, 2:40 AM

#

do you know cosine law

analog plank Aug 10, 2023, 2:40 AM

#

yep

empty quartz Aug 10, 2023, 2:40 AM

#

ah ok

#

how can you use it here

analog plank Aug 10, 2023, 2:41 AM

#

uhh

#

But

#

how

rn_image_picker_lib_temp_97e388df-a3f7-406c-954d-79c9983c5003.jpg

#

there is 2 unknown varible

analog plank Aug 10, 2023, 2:52 AM

#

empty quartz you have two side lengths of a right triangle, you use….

but there is no given value

#

how do i

empty quartz Aug 10, 2023, 2:53 AM

#

analog plank there is 2 unknown varible

how do you find two variables?

analog plank Aug 10, 2023, 2:53 AM

#

idk

empty quartz Aug 10, 2023, 2:54 AM

#

analog plank but there is no given value

just make up a random value for the side as the angle will be the same for all cubes (can you see why?)

analog plank Aug 10, 2023, 2:54 AM

#

Oh

#

wait

#

i cant do that cant i

#

wait

empty quartz Aug 10, 2023, 2:55 AM

#

analog plank im so done my ass is not passing gcses

you could just do it in terms of x as you’ve done here

analog plank Aug 10, 2023, 2:56 AM

#

i can use SOH or CAH right its the same

#

or TOA

empty quartz Aug 10, 2023, 3:31 AM

#

analog plank or TOA

well which sides of the right triangle do you know

analog plank Aug 10, 2023, 3:31 AM

#

i dont know anymore

#

i give up

#huh??????
