A 15 foot board rests against a wall. The angle that the board makes with the ground is 60 degrees . How far is the base of the board away from the wall

Hi y’all i want you my mom i

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.

It would be 3x+3 because the skate rental is for the day and she spent 3 hours skating. hope this !
