trigonometry (3D)

[lofty bison]

Im NOT sure where I made a mistake in my working out to find the length of ‘h’

[tired hollow]

you can't do that conversion from tan to cot, if you had simply solved from when you had $h^2 = \frac{100^2}{cot^2(62)+cot^2(55)}$

agex

[lofty bison]

Wait wdym

then how do i find h?

[tired hollow]

you can just square root that

[lofty bison]

with the cot?

[tired hollow]

is this non calc?

yes

[lofty bison]

yeah

[tired hollow]

ah

[lofty bison]

wait so i square root the whole thing?

[tired hollow]

even still

yes

[lofty bison]

but how do i calculate cot on the calculator

[tired hollow]

I found h=109.72

[lofty bison]

uhh wait lemem check the answers

[tired hollow]

1/tan(x) does the trick

providing you're not computing tan(nπ/2)

[lofty bison]

its supoised to be 114m

[lofty bison]

ohh okay

[tired hollow]

hm

oh I know why, my calc was in rad

💀

113.74

[lofty bison]

ohhhh okay

thank u

[tired hollow]

no problem
