Question

1. Draw a 30-60-90 triangle. Label all angle measures and side relationships. Using the side relationships from the figure, show that the following trigonometric identities hold true for the given angles:

Answer 1

tan 60=sin 60/cos 60

Answer 2

i know it is true, but why

Answer 3

\[\sin ^{2}(30)+\cos ^{2}(30)\]

Answer 4

ummmm
im not doin tricanometry or geometry so
im sorry
:(

Answer 5

and this too
i got the triangle and the sides

Answer 6

its alright :)

Answer 7

now from the graph you would know
cos 60 =A/C
sin 60=B/C
tan 60 =B/C



now
sin 60 / cos 60 = B/C *C/A=B/A=tan 60
does this make sense to u ?

Answer 8

nop

Answer 9

i made a typo on the graph :P
it should be like this


ok ill do from skratch

Answer 10

ok u have this triangle with sides A,B,C
with me so far?

Answer 11

yes

Answer 12

so
sin 60 = Contrast /hypotenuse=B/C

right ?

Answer 13

yes

Answer 14

could u find cos 60 and tan 60 as well ?

Answer 15

i believe cos 60 = c/a?

Answer 16

and tan60 = a/b

Answer 17

well cos theta =adjacent /hypotenuse = A/C

Answer 18

cos 60 =A/C

Answer 19

and
tan 60 = adjacent /Contrast

Answer 20

so tan 60 =B/A ok ?

Answer 21

oh okay, so, do you mind helping more, like what are the sides?
