Question

In triangle STU, SU = 18 and TU = 13. Find m 12 years ago

Answer 1

is it a right triangle?

Answer 2

okay lets see hmmm

Answer 3

this is literally an example of what I just asked like 10 minutes ago if you can find the missing angles in a right triangle if you have some of the langths

Answer 4

By using the tan formula:

tan (angle) = (opposite side) / (adjacent side)
tan (T) = SU / TU
T = tanh (SU / TU)

Hope this helps.

Answer 5

@dauspex how does tangent find angle measures though, I forget?

Answer 6

UGH. I'm not getting any of this.

Answer 7

tan (T) is actually a ratio of the sides of a triangle
