Answer:
The choice third ; a=9 , c= 18
Step-by-step explanation:
![\sin(60) = \frac{9 \sqrt{3} }{c} \\ \\ c = 18](https://tex.z-dn.net/?f=%20%5Csin%2860%29%20%20%3D%20%20%5Cfrac%7B9%20%5Csqrt%7B3%7D%20%7D%7Bc%7D%20%5C%5C%20%20%5C%5C%20c%20%3D%2018%20)
![\tan(30) = \frac{a}{9 \sqrt{3} } \\ \\ a = 9](https://tex.z-dn.net/?f=%20%5Ctan%2830%29%20%20%3D%20%20%5Cfrac%7Ba%7D%7B9%20%5Csqrt%7B3%7D%20%7D%20%20%5C%5C%20%20%5C%5C%20a%20%3D%209)
Answer:
(1,2) is a solution to both equations
Step-by-step explanation:
To determine if (1,2) is a solution to both equations, substitute into the equation and see if it is true
2x+y =4
2(1) + 2 =4
2+2 =4
4=4
true
y =3x-1
2 = 3(1) -1
2 =3-1
2=2
true
Since both statements are true
(1,2) is a solution to both equations
