Question

Approximate using a calculator the two values of angle u (0°≤u<360°).
Sinu= .8191

Answer 1

Could you clarify your question? >_>

Answer 2

It wants two angles that have the sin of .8191

Answer 3

\(\large \sin(u) = .8191\)

\(\large u = \arcsin(.8191)\)

Answer 4

So .9598???

Answer 5

Is it in the right mode? >.>

Answer 6

Its in degrees. Should it not be??

Answer 7

^^u = 55 degrees

Answer 8

Answer 9

I was actually in the wrong mode xD Thank you guys

Answer 10

You're welcome :3

Answer 11

np :)
remember u need to find one more angle...

Answer 12

Just add 180~

Answer 13

for tan adding 180 wil work
but for sin, we can do this : sinu = sin(180-u)
so, if 55 is one angle, other angle wud be 180-55
