Question

SORT of easy trig problem?? PLEASE?☟^◕‿◕^
If sin Θ = 15 over 17, use the Pythagorean Identity to find cos Θ.

Answer 1

Here are the possible answers:

Answer 2

hypotenuse =17 perpendicular =15
base =8
cos x =base/hypotenuse

Answer 3

Doesn't that only work with triangles? SOrry I am clueless about trig lol

Answer 4

My openstudy is glitching rn so sorry for slow replies..

Answer 5

@nechirwan Can you do this?

Answer 6

sin x=perpendicular/hypotenuse

Answer 7

in right triangle hypotenuse^2=base^2+perpendicular^2

Answer 8

Answer 9

SO how do I apply that?

Answer 10

with sin x find perpendicular and hypotenuse then find base

Answer 11

So 15^2+8^2

Answer 12

K give me a sec

Answer 13

hypotenuse would be 17?

Answer 14

and then 8/17

Answer 15

Ohhh

Answer 16

Thankyou!
