Question

Solve the following:

sin(x)= -3/4

SO far I got this:
arc sin (-3/4) = -49.6 degrees
it's in Quad 3 and 4 so the 2 angles I got are 228.6 and 131.4

Answer 1

I'm getting arcsin(-3/4) = -48.59

Answer 2

also, 131.4 degrees is in quadrant 2 (since it's between 90 and 180)

Answer 3

I'm sorry, typo ur right on the arcsin

Answer 4

I did get 228.6 for one of the answers

Answer 5

I think I was confused on the quadrants for a second

Answer 6

as confirmation

sin(228.6) = -0.75011 approximately

Answer 7

It should be quad 1 and quad 4

Answer 8

no, quad 3 and 4

Answer 9

sine is negative here

Answer 10

uh now I'm confused on this again

Answer 11

48.59 is in Q1

Answer 12

any angle in Q4 is between 270 and 360
