@dan815 Can you help with this one?

OpenStudy (anonymous):

A and E are the same angle so they have the same sine

OpenStudy (anonymous):

Okay, but I am unsure how to find that...

OpenStudy (anonymous):

how to find the sine or how to find that they're the same angle?

OpenStudy (anonymous):

"If sin A = 0.5..."

OpenStudy (anonymous):

So does that mean it's also .5?

OpenStudy (anonymous):

yes
