4x+499=660
X=40.25
X equeals the amount for each game.
Step-by-step explanation:
Let alpha be the unknown angle. We can set up our sine law as follows:
![\frac{ \sin( \alpha ) }{5 \: m} = \frac{ \sin(42) }{3.6 \: m }](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Csin%28%20%5Calpha%20%29%20%7D%7B5%20%5C%3A%20m%7D%20%20%3D%20%20%5Cfrac%7B%20%5Csin%2842%29%20%7D%7B3.6%20%5C%3A%20m%20%7D%20)
or
![\sin( \alpha ) = \frac{5 \: m}{3.6 \: m} \times \sin(42) = 0.929](https://tex.z-dn.net/?f=%20%5Csin%28%20%5Calpha%20%29%20%20%3D%20%20%5Cfrac%7B5%20%5C%3A%20m%7D%7B3.6%20%5C%3A%20m%7D%20%5Ctimes%20%20%5Csin%2842%29%20%20%3D%200.929)
Solving for alpha,
![\alpha = arcsin(0.929) = 68 \: degrees](https://tex.z-dn.net/?f=%20%5Calpha%20%20%3D%20arcsin%280.929%29%20%3D%2068%20%5C%3A%20degrees)

A-P-E-X QUIZ
Answer:
19
Step-by-step explanation:
X will refer to the number.
X+57( the number added to the original.)=4x. (x time 4)
X+57=4x.
Subtract x from both sides to get the variable on one side.
(X+57)-x =(4x)-x
57=3x. You would then divide by 3 on both sides to again get integer isolated.
57/3=3/3x.
57/3=19. 3/3=1.
19=x.
