Question

Please help! if θ is an acute angle and sin θ= 1/2, then cos θ=

A. -1
B. 0
C. 1/2
D. √3/2
E. 2

Answer 1

You'd basically find the inverse of it so I THINK it is E, but I could be wrong.

Answer 2

Okay I think So too... thanks :)

Answer 3

yes @xMissAlyCatx so i think it same wrong your answer because where sinß = 1/2 so this mean that ß = 30° so what will resulted for cosß = sqrt3 /2
- so i think that from this result D. answer will be correct

hope this is understandably and will help you

please correct your answer

@Kfsv10 hope this will help you understanding

Answer 4

Well like I said @jhonyy9 , I wasn't sure... soo..
