The solution would be like
this for this specific problem:
Given:<span> x +y
= 390 </span>
2x + 4y = 1260
2x+4y=1260 ßdivide by 2
= x+2y=630
x+y=390 ßsubtract
= x+2y-x-y=630-390
y=240
x+240=390
x=390-240=150
<span>So, if they raised $1260 from the concession
stand, then they sold 240 sandwiches.</span>

Answer:
Step-by-step explanation:
It's a 30-60-90 triangle. The sides of a 30-60-90 triangle are in the ratio 1:√3:2
The side opposite the 90° angle is 12√3, so the side opposite the 30° is (12√3)/2 = 6√3.
The side opposite the 60° angle is (6√3)√3 = 18
x = 18
y = 6√3
