First draw out the picture it will help. Then you can see that you want the opposite segment of the angle, which leads you to use a sine. So you have 20sin30 or 20(1/2) or 10ft.
Ok so you divide the bill by 2 because you each are paying half. You knock off $4 because you owed him that from last time and you pay $9. So this would equal to b/2 -4 =9. If you work it out in reverse, you get 4+9 which equals 13 then multiplied by 2 which means the total bill was $26.
So we have 5+3x=11. We subtract 5 from both sides and get 3x=6. we divide both sides by 3 and get x=2. Daniella skated for 2 hours
Answer:
lets consider two end points are the marked points ,
Then ,
(1,5)=x1,y1
(-1,-3)=x2,y2
line passes through point(1,0)=x3,y3
slope of line ,m = (y2-y1)/(x2-x1)
= (-3-5)/(-1-1)
=4
Eqn of line is:
y-y3=m(x-x3)
y-0 = 4(x-1)
y=4x-4
4x-y=4 is reqyuired eqn..
