Answer 1

Answer:

Step-by-step explanation:

Answer 2

So uhh in my school we use this thing “Soh Cah Toa.” Soh=sin, Cah=cos, and Toa=tan. o=opposite h=hypotenuse and a=adjacent side. And we use the give angle. So the opposite side is AB. So it’s either Soh or Toa. Now we’re finding the hypotenuse so it’s Soh, because it has o and h.
So it’s gonna be choice 3.
(Might wanna double check with someone else, cuz I’m also in the middle of Trig unit)
