Can someone me solve this do i use sin cos or tan?

X= 2 sq rt 3
Y= 3. Sqrt 3 times sqrt 3 =3

U should use sin and tan.

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
